In order for different Vegtables, Fruits and Herbs to grow successfully one needs to manage carefully the key elements to Hydroponics. From the outset, to name but a few: the means of seed germination; grow media; as the seeds germinate and start to sprout their relative climate both room and water temperatures [which are different]; the level and proximity of lighting; the introduction of nutrients with too little leading to wilted and yellowish leaves, while excessive darker green and curving leaves indicate excess nutrients all are critical to the difference between strong healthy plants and weak and those dead from-the-get-go.. Delicate management is mapped out in the stages below, while the Key Elements page provides more detail.
Avoid Overwatering: The biggest mistake is keeping the rockwool too wet. Never let the cubes sit in a puddle of standing water; ensure proper drainage.
Bottom Watering: Placing the cubes in a tray with a small amount of water (about 1/4 inch) can be an effective way to keep them moist without over-saturating the top.
Keep the sprouts covered: Cover all the holes; keep the grow dome/transparent cover on until the plant is closer to the top of the limited grow dome; ensure there are one or two active roots. .
Removing the protective grow dome/ transparent cover: Leaving this on for too long can lead to Fungal growth/mold and diseases like "damping off" due to 100% humidity and lack of air circulation; Leggy, weak plants as they stretch for light blocked by the dome/cover; difficulty acclimating to the normal humidity of the growing environment later on; Timing is Key: The purpose of the grow dome/ transparent container lid covering is to create a humid micro-greenhouse to aid in initial germination. Once the plant has sprouted, it needs air circulation and direct light.
Ensure Airflow: After removing the grow dome/ transparent container lid, ensure the seedlings have proper air circulation, possibly by using a gentle fan, to help strengthen the stems and prevent disease.
Monitor Moisture: Without the grow dome/ transparent container lid, the growing medium will dry out faster, so monitor moisture levels closely and water as needed (often from the bottom to encourage root growth).
Stage 2 to 4 is outlined according to individual plants. One can view a whole variety of Vegetables, Fruits and Herbs and their specific requirements, the resulting most appropriate Hydroponic system of choice and how to successfully navigate their stages of growt via the the Plant Choices page.
In controlled circumstances where Key Elements are in balance one can see real seed germination very quickly. One can achieve seemingly good growth in warmish environment plenty of grow lighting, fresh changes of carefully timed water, with gradual introduction of low level of nutrient solution. However, if one of the key factors of growth i.e. Oxygen to roots is missing this is the least concerning, but by 6 weeks in roots will be browned and starved. Growth will be limp and not at the rate of growth where all the key factors are at the right levels.

hydroponic growing system provides aeration through a built-in water pump that circulates water and oxygen to the plant roots. This continuous or interval-based circulation is essential because, in a soil-less system, the roots need direct access to dissolved oxygen to prevent drowning and ensure healthy growth.

Wait for your seedlings to develop their first set of true leaves before adding nutrients. The first two leaves are seed leaves (cotyledons) and contain enough energy to support the seedling until true leaves, which are larger and more functional for photosynthesis, emerge. Adding a half-strength nutrient solution is a good starting point.

Critical Rockwool for seedling management In the first stage (germination and early seedling growth), rockwool cubes should be kept moist, but never soaking wet or completely dry. The goal is to provide enough moisture while ensuring plenty of air is available for the roots to develop, preventing root rot.

Nutrient relevant levels https://www.twinkl.co.uk/resource/t2-s-158-plant-growth-prediction-worksheet What does a plant need to grow? Plants need 5 things to grow: water, light, nutrients, air, and space to grow. However, different types of plants need different amounts of each of these things, and some may have very specific needs to stay healthy - for example, a rose bush has much more specific needs than a dandelion! Here's a short breakdown of why each of these things is important: Water. Plants need water for photosynthesis. Absorbed by the roots, water travels through a plant’s stems to the chloroplasts in the leaves. Water also helps to carry nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop, but on the flip side, too much water can cause a plant’s roots to rot. Plants can absorb small amounts of water through their leaves, but they get most of the water they need through their roots. Light. Plants usually get the light they need from the Sun, but they can also grow in artificial light. Plants use light energy to make a type of sugar called glucose, which they use as their energy source. Plants make glucose in a part of their leaf cells called the chloroplast. Each chloroplast contains a green pigment called chlorophyll - this is what allows the plant to absorb light energy. Lumens (lm) measure the total light output from a source (brightness), Lux (lx) measures light intensity on a surface (1 lux = 1 lumen/m²), and Kelvin (K) measures the color temperature (warm to cool) of the light, with higher Kelvin being whiter/bluer and lower Kelvin being warmer/yellower. Think of Lumens as the total water from a hose, Lux as how wet the ground gets in a specific spot, and Kelvin as the color of the water (though it's light, not water!). Lumen (lm) What it is: The total amount of visible light emitted by a source (e.g., a bulb). How to use it: More lumens mean a brighter bulb. Lux (lx) What it is: Illuminance; the measure of light falling on a surface (1 lumen per square meter). How to use it: Important for task lighting; tells you how bright a desk or countertop actually is. Kelvin (K) What it is: Color temperature; describes the perceived warmth or coolness of light. How to use it: Lower K (e.g., 2700K) is warm/yellow; higher K (e.g., 5000K+) is cool/blue, affecting mood and alertness. Key Relationships Lumens & Lux: You need lumens from a bulb to get lux on a surface, but lux depends on the area and direction, while lumens are the source's total output. Kelvin & Brightness: Kelvin defines the color, not the total brightness (lumens), but color temperature influences how bright we perceive light.

Nutrient Basics
Add the A & B nutrients in equal proportions. Most typically it's recommend 5ml of each (A & B nutrients) added to each 1 liter of water that one adds to the system. One can buy more A & B nutrients from any good outlet - these are more or less identical in composition, so buy the cheapest bundle - e.g. https://www.amazon.com/Hydroponics.../dp/B0C38RY6JP Once one has more experience, it’s worth buying better nutrients that are targeted to specific types of plants. Above all else don't overdo nutrients. Stick to the recommended proportions and read up on other nutrients before spending more money. Reddit has some excellent discussions on nutrients, e.g. https://www.reddit.com/answers/4214afc3-606d-4758-8094-2e364c8a340a/?q=Hydroponic%20plant%20food%20comparisons
Fulvic Acid helps with nutrient chelation (especially micros) and can improve uptake and stress tolerance. Add it after one's base nutrients are fully mixed, then adjust pH last. Use sparingly. A little goes a long way. Make sure it’s fully soluble / hydroponic-grade low-sediment ,no grit or sludge settling out. Avoid “fulvic/humic” products made for soil, since they can gunk up lines and reservoirs.PH, EC, and PPM
You first have to understand the concepts of pH, EC, and ppm in order to determine how it affec6s your plant's growth and development what your plants need. Tons of info on youtube that will guide you. If you are not measuring pH and EC, start doing that right away. Watch these two parameters closely. Low EC means you need more nutrients. PH out of range means you are LOCKING up certain nutrients avg are gonna show signs of a deficiency, even though the solution has plenty of nutrition. Get a good PH/EC meter. I find much less trouble from PH MONITORS rather than testers. The monitor stays submerged in your reservoir providing constant PH and EC data. The tester, on the other hand, must be kept in a storage solution.... Nobody ever does this and they always complain about their tester dying.
Ph Drop reasons In my experience, when pH has been stable and then suddenly starts dropping, it is often linked to biofilm or microbial activity developing in the system. While this is an oversimplification, a delayed pH drop usually indicates that organic material or microbial byproducts are accumulating in the reservoir and producing acids. By contrast, when pH drifts upward toward alkaline, it is usually related to carbonate alkalinity or dissolved minerals in the water, which buffer and neutralize acids. This is more common when using tap water, where bicarbonates are present. PH level depends on several factors, especially system volume and how well the water is managed. For a 1‑gallon or X liter system, weekly changes make sense because the water gets “used up” quickly. For systems up to about 5 gallons, a 12–14 day interval is usually fine. Once you’re at 6 gallons or more, you can typically run 25–30 days between changes. With good water care—strong circulation, proper oxygenation, stable nutrients, and a conditioner to keep the pH in range—you can often go even longer, as long as the water stays stable and doesn’t get exhausted. Biofilm/algae in channels is usually responsible. Ph7 = 10X alkaline as Ph6, Ph8 = 100X as alkaline as Ph6. Typically ph trends higher over time, requiring acid/ph down but the fact its rising that high so fast suggests something is amiss, but no idea what that could be. That shift is unusually extreme. What are the inputs into the nutrient solution over time ? Rather than ph adjusting your input water - get that recirculating solution 1st to ph6. It may be you simply havent corrected the recirculating solution intially, and the tiny amount of ph down you're putting into each bucket of water simply isnt nearly enough in the first instance. Get that recirc nutrient at 6 FIRST, then add as much ph down required thereafter to keep it there...or really anything between 5.5 and 7 is likely going be fine. Precise numbers not so important as being within a target range....and managing the trend. If you add only water but not nutrients, the pH will go up. The ration of nutrients to water decreases with each add. Many people like to prepare a jug of water with the nutrients added to it. That way you always feed the proper amount. I've recently tried this in one of my self-watering systems. So far so good! 2 factors can raise the ph pretty high. The plant itself and a air pump as it adds oxygen. What you need to do is check it daily and adjust accordingly until you get it stabled out. also something to keep in mind is if you add nutrients then the ph of those nutrients will increase the next day and should start evening out afterwards

https://ugf.onl/blogs/guides/water-change-indicators ph raises due to ion changes in the water. Ions comes from som e plants (like spinach), Algeas or it could be that the buffer in water is reported and low. Easiest is to change the water once every week. I found a good aquarium buffert for ph 5.5. it works great but gives slight salty flavour to my herbs. If you do herbs or microgreens starving for Iron then ph 5-5.5 should be what you aim for. They are *not* buffered. They are also nitrate-based, which can raise alkalinity. I use all three regardless of whether I have flowers. Also, make sure you mix in the right order (silicon, calmag, micro, bloom/phosphorous, gro), then adjust PH. FINESSE AND ADD TO A NAME NFT STYLE PAGE CALLED BEST WATER>.... i grow tomatos strawberries,pepper plants and peas. i have used the floraseries and maxigrow/maxibloom. i have noticed the best outcome and the healthiest looking plants by using the plant food A and B that comes with most of these aerogardens. i use the recommended dose stated on the bottles and at 1tsp of 3% food grade h2o2 per gallon of nutrients and that prevents root rot. That is something to think about in the future if you ever decide to switch but regardless whatever you have success with then do that. alot of plants, no wonder your chemistry is changing so fast. Lots of feeders for only 50 liters. In my kratky I use 10 salads for 30 liters. Fruiting plants feed more when flowering. are there everyday substances that will bring the ph down for my leafy greens solution +9 Yes, white vinegar (acetic acid) and fresh lemon juice (citric acid) are common household substances that can temporarily lower the pH of your leafy greens' nutrient solution. How to Use Add slowly: These are concentrated, so add a very small amount (e.g., a few drops or a 1/2 teaspoon per gallon of water) at a time. Stir and test: Thoroughly mix the solution after each addition and wait a few minutes before using a reliable pH meter to check the new level. Repeat as needed: Continue adding small amounts until the target pH range of 5.5 to 6.5 for leafy greens is achieved. Important Considerations Temporary effect: Organic acids like vinegar and lemon juice offer a less stable, short-lived pH adjustment compared to commercial mineral acids (like phosphoric acid). The pH tends to rise again within a couple of days because the plants and microbes can consume the organic compounds, so the solution will need more frequent monitoring and adjustment. Nutrient imbalance potential: Frequent use of large amounts might impact the overall nutrient balance (EC) of your solution or encourage microbial growth in a hydroponic system, which can be problematic in a recirculating system. Commercial products are recommended: For the most stable and reliable results, commercial pH down products (often food-grade phosphoric acid) are specifically formulated for hydroponics and are available at garden centers. Using vinegar or lemon juice is a good emergency or temporary fix for small home systems or a single watering, but for a consistent, long-term solution, a dedicated hydroponic pH adjustment product is best.Nutrient Mixing

You can buy pre-made solutions as liquids or powders or create your own by combining them with purified water. The solution must be carefully balanced for pH and EC (electrical conductivity) to ensure plant health. Key components Macronutrients: The "big three" are nitrogen, phosphorus, and potassium (NPK), which are vital for leaf growth, roots, and overall plant health. Other important macronutrients include calcium, sulfur, and magnesium. Micronutrients: These are needed in smaller amounts but are still critical. They include elements like iron, manganese, zinc, and boron. Base nutrients: You can buy these in liquid or powder form, which are specifically formulated for hydroponics. A common example is a balanced NPK fertilizer like 20-20-20, along with other components like calcium nitrate and Epsom salt (magnesium sulfate). How to create a solution Use purified water: Start with water that has been purified, such as by a reverse osmosis (RO) system, to ensure a clean and predictable starting point. Mix nutrients: Follow the instructions for your chosen pre-made kit or a DIY recipe. For example, a simple DIY recipe might involve mixing a specific amount of a water-soluble NPK fertilizer, calcium nitrate, and Epsom salt into a gallon of water. Check and adjust: After mixing, check the solution's pH and electrical conductivity (EC) levels. The ideal pH is often between \(5.5\) and \(6.0\) for many plants. You may need to add a pH-up or pH-down solution to get it right. Maintenance Regularly add water: The water level in your hydroponic system will decrease due to transpiration and evaporation, so you'll need to add water to maintain the correct level. Perform regular solution changes: It is necessary to completely replace the nutrient solution in your system every one to three weeks, depending on the size and type of system and the growing environment. This prevents a buildup of unused salts and nutrients.
EC, or Electrical Conductivity , in hydroponics is a measurement of the total dissolved salts and minerals (nutrients) in the water solution, indicating its concentration strength. A higher EC means a more concentrated nutrient solution, while a lower EC means the solution is more diluted. Proper EC levels are crucial because too low a concentration can lead to nutrient deficiencies, while too high a concentration can lead to nutrient toxicity and root damage. This video explains the basics of EC and its importance in hydroponics: 40sBright Lane GardensYouTube • 16 Nov 2023 What EC indicates ...Nutrient concentration: EC is an efficient way to gauge the overall strength of the nutrient solution without having to test for each individual nutrient. Plant health: It helps ensure that plants receive the right amount of nutrients for healthy growth without becoming toxic. Plant needs: Ideal EC levels vary depending on the plant type and its stage of growth. Seedlings and leafy greens need a lower EC, while fruiting plants like tomatoes require a higher EC. Why monitoring is essential Too low (< 1.0 mS/cm): The solution is too diluted, and the plant may experience nutrient deficiencies. Too high (> 3.0 mS/cm): The solution is over-fertilized, which can cause nutrient burn, salt toxicity, or prevent the plant from taking up enough water, leading to wilting. Ideal range: A general target for many mature plants is around \(1.8\) mS/cm, but this can vary significantly by crop. This video explains how EC levels affect plant growth:05:15AirgardenYouTube • 9 Dec 2022Measuring and adjusting Use an EC meter: A handheld EC meter is used to measure the electrical conductivity of the nutrient solution. Adjust as needed: If the EC is too high, you can add more water. If it's too low, you can add a concentrated nutrient solution. Monitor regularly: Consistently monitoring the EC allows you to make small adjustments to maintain the ideal level for your plants.

Healthy Roots
Some roots are darker than others but 3% food grade hydrogen peroxide will cure root rot and prevent it. I add 2 tlbs per gal of water/food to my hydroponic system it keeps my roots beautiful and my system clean and it also has a lot more benefits. You can add up to 3 tlbs if you already have root rot. You can do that for a few weeks and drop it down. f the dark roots are soft and mushy (Root rot) then that is degradation due to microbial action and isolation from other plants may be a good idea. Vinegar will not be sufficient so a bleach will be better and since hydrogen peroxide breaks down into oxygen and hydrogen these are two of the top nutrients plants are physically made with so the benefit works both ways along with the minerals you use. Review your nutrients and buying hydrogen peroxide in a stronger solution such as 35% will be more economical as you can dilute to 3% or stronger of course caution when handling is advised. Food Grade Hydrogen Peroxide: https://www.amazon.com/dp/B0B1LBCQYL?ref=cm_sw_r_cso_cp_mwn_dp_KCYX384S5VN648V5RJ7E&ref_=cm_sw_r_cso_cp_mwn_dp_KCYX384S5VN648V5RJ7E&social_share=cm_sw_r_cso_cp_mwn_dp_KCYX384S5VN648V5RJ7E&titleSource=true the frequency of changing the water weekly is what giving you that results. Like linda said, weekly is overkill and waste. Everytime you do that, you shock the plants. Some may be more resilient than others. Just top up and perhaps change monthly.
Key other things where
Don’t grow fruiting vegetables (peppers, tomatoes) and non-fruiting vegetables (herbs, lettuce, etc) together. Know how big your plants will get so you know if your lights raise high enough for height and width of them. Don’t put too many plants in one garden. Grow my own seeds and not use pre-seeded pods. Nice set up! Clean water healthier plants. Reverse osmosis water is more clean than tap. Less particles means no barriers for nutrients to get to roots. Enzyme cleansers at flush and feedings. SLF 100 is organic and works great. Liquid food is easier to work with. PH maters for nutrient absorbance. Usual PH for veggies 6.5. Flush once a month, keep tank topped off. Cal- mag helps plants along with liquid fertilizer. Great starter system. I would highly suggest just growing leafy greens and herbs. Use this system to learn basics of hydroponics such as PH, EC, environmental management. Check parameters every day or 2 and keep a record. Patterns will emerge when compared to growth and plant health. Enjoy the journey, welcome to hydroponics 👍 I have Zero Water filtered pitchers that work great and minimize hard water buildup. Citric acid in water helps when cleaning your garden for buildup that’s difficult to get off. If you ever want to get more technical, I check pH and EC and add nutrients based on the readings. Different types of plants have different pH and EC requirements. It’s another way to determine if you can put certain plants in with each other - if they require the same or similar EC and pH.
Water temperature is the quiet deal-breaker in hydroponics. Warm water holds less dissolved oxygen, so roots start suffocating and you get the classic “mystery problems” (slow growth, droop, yellowing, slime/biofilm, root rot). Once you’re regularly above 24°C (75°F), issues ramp up fast. Your water is NOT the same as room temp. Plastic kit/tabletop systems can run warmer than the room because the lights heat the plastic and lid, and the submerged pump adds heat too. So your “72°F room” can still be “78°F water” without you noticing. If one has consistently warmer enviroment then areation becomes a vital factor. Having a standard hydroponic grow system pump for breaking the water and aiding circulation isn’t enough to properly oxygenate the reservoir. A range of affordable to sophisticated aquarium air pump + air stones keep dissolved oxygen up, helps roots stay white and healthy etc.

This depends on the given plant and size of the reservoir. You should fully change the nutrient water for lettuce in a hydroponic system every 1 to 3 weeks. In addition to regular changes, monitor and adjust pH, nutrient levels, and water levels, and top off with water as needed between changes. Full water change Every 1 to 3 weeks: A complete change of the nutrient solution is necessary to prevent nutrient imbalances and the buildup of pathogens. Every 2 weeks: A good rule of thumb for leafy greens like lettuce is to change the solution every two weeks. Every 3 weeks: In larger reservoirs changing the water every three weeks for lettuce will suffice. Between full changes Monitor and top off: Check the water level daily and top off with plain water as needed to keep the level stable. Measure and adjust: Regularly check and adjust the pH and EC (nutrient strength) of the solution. Perform a full change if needed: If you notice issues like a bad smell, algae, or significant changes in pH or EC, perform a full water change sooner than scheduled.
First feeding is after true leaves form. Perhaps the PH is too acidic or neutral. Research the ideal PH for herbs and adjust. Use uv stickers those herbs may have too much light and it prevents algae. You can do a light dose of fertilizer but if your roots have build up on it they will not absorb. Use an enzyme cleanser like SLF 100 it will remove build up. What is your water source? The more clean the water less obstacles the plants have to go through to get nutrients. I use reverse osmosis water, adjust PH to 6.5 add slf 100 at flush and feeding.

Basic Mould Management Okay, you actually have a few issues here. First I'll help you understand why you have the problem then how to fix it. First, you already have plants growing in your system, which means you already have nutrients in the reservoir. The seed you’re trying to germinate should NOT be in the system. Here’s a guide that walks you through proper germination 👉 https://ugf.onl/blogs/guides/seedstarting And here’s another guide explaining why you should never germinate seeds inside *any* grow system 👉 https://ugf.onl/blogs/guides/start-strong As for what’s growing on your sponges — that fuzzy white stuff is mold. It’s caused by the combination of nutrients + water + light + VPD out of range. You can check whether your VPD is in the correct zone using this calculator 👉 https://ugf.onl/pages/vpd-calculator How do you improve this? 1. Check your environment — This is where VPD matters. 2. Improve air circulation around your system. A small fan helps a lot. As your plants grow, keep up with pruning to maintain airflow. 3. Check your EC levels. 4. Check your pH and keep it between 5.8–6.2. Keeping these metrics in range strengthens your plants and reduces the chance of infections. How to remove it? You’ll need to treat this—if you don’t, it will spread. Fixing the metrics above will help, but you still need to knock down the mold directly. 1. Improve airflow. 2. Hydrogen Peroxide Treatment Using a fine‑mist sprayer, mix a batch of food‑grade hydrogen peroxide like this 👉 https://ugf.onl/products/peroxide6 :: 1 teaspoon (5 mL) of 6% peroxide per 1 cup (240 mL) of clean water :: THIS IS FOR 6% FOOD-GRADE 3. Citric Acid Treatment If you have citric acid, you can use that as well. :: 2% w/v citric acid = 2 grams per 100 mL of warm water (or 20 g per liter) :: Spray the tops lightly twice a day with a fine mist. It should clear up in a few days. If you need more help, please feel free to reach out to us directly.
Nutrients. Nutrients are chemicals that the plant needs to stay healthy, just like humans do (although they need different ones to us). In particular, plants need nitrogen, phosphorus and potassium. When dissolved in water, these nutrients get absorbed by a plant’s roots and delivered to the rest of the plant. Air. Air contains many gases. They include nitrogen, oxygen, carbon dioxide, and water vapour. Using energy from light, plants chemically combine carbon dioxide and water to create glucose and oxygen. This process is called photosynthesis. Plants also absorb oxygen gas from the air. Like animals, plants need oxygen to respire. Respiration is the process of breaking down molecules, like glucose, for energy. Space to grow. All living things need space. A plant’s roots need space so that they can spread out and absorb water and nutrients, and its leaves need space so that they can get access to light. When plants grow too close together, they have to compete for these resources. Without enough water, nutrients, and light, plants can grow tall and thin or short and stunted. Overcrowded plants tend to be less healthy, which makes them more likely to suffer from diseases. Most A/B base nutrients already include enough calcium and magnesium for normal growth. Cal-Mag is mainly something you add when you’re actually seeing a deficiency (ex: interveinal chlorosis, yellowing on older leaves, tip burn/new growth issues), or if you’re using RO/very soft water. If plants look good and EC is already in range, adding Cal-Mag “just because” can push EC too high and cause nutrient imbalance/lockout. Your plants look good, you don’t need it. If anything look like over feeding a bit. Would lower Ec a couple tenths of a point. 👍 also keep in mind Fruiting plants need an A&B Bloom nutrient when flowering (more phosphorus/potassium) most system are shipped with just A&B Grow formula (more nitrogen) as they are intended for non fruiting plants. PH range (5.5-6.5) is universal for all plant types, EC is what fluctuates with different plants and ages. Cal-Mag isn’t a “fruiting” nutrient or additive. it’s just calcium and magnesium, used when a deficiency is present. (Popular because its the most common deficiency due to environmental stress) Most A/B nutrients already include calcium and magnesium, that’s often why they’re split into A and B. Yes, base A&B (grow) doesn’t have what fruiting plants need. That's higher phosphorus and potassium. A&B bloom formula does, including more calcium and magnesium for fruit development. Adding Cal-Mag on top when it’s not needed can throw the balance off and cause uptake issues. Trust me, have done it many times, its not good. All you need is a A&B bloom formula for fruiting plants (flowering stage), no calmag. Adding liquid Cal-Mag now will not harm the plants or disrupt your existing A & B nutrients. However, it will slightly raise EC and often shift pH upward. As long as your plants can tolerate the small EC increase and you recheck and adjust pH afterward, it is safe to add. Cal-Mag is not a neutral addition, so monitoring and correcting pH is part of the process. Increase where lacking airflow around the plant a bit, not hurricane, just gentle leaf movement and put an aquarium air pump and stone in the tank. Tomatoes love more oxygenation. Enjoy the journey, doing good 👍 https://a.co/d/frgW7my

Flowering Phase and Stretch Phase (does this phrase apply beyond the dodgy green stuff)...
https://www.420magazine.com/community/threads/everything-you-need-to-know-about-flowering-stages-through-when-to-harvest.540063/ It’s an okay veg/grow formula if you add Cal-Mag. Once flowering starts, I’d stop using this and switch to a proper hydroponic A&B Bloom formula. Bloom nutrients are lower in nitrogen and higher in potassium and phosphorus, which helps signal the plant to shift from leafy growth to flowering/fruiting. When you’re on a good bloom formula, you can usually stop the Cal-Mag supplement (unless you’re actually seeing a deficiency)

Don't cut corners on lighting. It's not worth buying the cheap seemingly effective at first. Not only do most fail to provide enough overall lumen (elaborated here), but they are often awkward to bend l, position or their lux area is limited with gaps in coverage. They're like throwing money away. Quality 5000k+ natural light adjustable fuller spectrum lights. Check the size of space available. If you get multiple band runs of light as is available via some reputable brands one can place as per need effectively.
