The dark color is looking like ph imbalance... intervein chlorosis looking like start of magnesium deficiency... depending on what u are feeding mabey ph related as well. Make sure to check ph. If ur not feeding magnesium.. feed some. Happy growing and stay lit fam.

Organic peat controlI think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?Leaves. Tips - Burnt

Black discolouration on leavesOkay so the problems with the black spots continue only on one plant. I tried reducing nitrogen and increased calmag to 4ml/g. I defoliated the affected leaves and sprayed with baking soda mix. 3 days later they're appearing again. If I don't get this fixed soon im gonna lose herWeek 2

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc.
I believe this may be nutrient burn?
