@IDontExist Hey there, it looks like a rocky start? I have been an outdoor organic farmer longer than it has been a thing. I had an alergic reaction to pesticides when I was young and the memory just stuck with me. I just avoided all pesticides in my control. I learned over many years that good organic living soil requires many many years of inputs to get to the desired results. Trying to achieve that indoors is a lofty goal but will come with many potential shortages. I used to carry soil indoors in pots from my garden but I have a bad back now 10+ years and that just is not an option. So I went hydro where pumps do all of the heavy lifting. Organic is not a good choice for hydro although possible it is hard to control the variables with enough speed to respond to the plants immediate needs. This is a long winded way of getting to my observation that your plants look hungry and could use 500-600 PPMs of MegaCrop. I think you can still get 500g for the price of shipping on Amazon. Lower your lights a bit also.
Do you have any Far Red LEDs 720nm (called an initiator puck)? If you run them for 15 minutes at lights out for 7 days it will encourage more stretch and you may be able to save something out of this grow. The clock is ticking.
