So now that I am aware of this I went back to the beginning and checked. This is the full Kellogg run correct? If so then I am not surprised looks like you are running into some of the same moisture and nutrient challenges that I did. In that other tent you got a blend going and they are looking better. Is this correct? You can still save these ones probably will loose the roughest looking one but the others aren't too bad. It does look to me like a
CalMag deficiency with that Space Wrangle. Im not 100% sure but pretty sure. I think if you raise the light up just a little to ease the intensity and also start adding a dose of
CalMag to your waterings it will self correct. Unfortunately
CalMag deficiencies are common when using LEDs and especially if you are using cheap soil also. If you want those plants that are lush dark green and healthy all the way through without having to add anything extra then you gotta pay for that more premium soil. Its a simple "you get what you pay for" scenario. Next time you do a HD run for soil you should consider mixing your own blend its way cheaper and IMO its just as good as if not better than most of the other premixed brands that they carry. Once I learned how to make my own soil blends I rarely ever buy the bag soils anymore.
