Hi all, this is my first time growing and I've been doing studying online for weeks.
My setups are:
-strain: unknown strains from friends from Paraguay
-4*2*5 ft growing tent
-100*3w LED light with red:blue 8:1
distance of the light to the top plant was about 12' yet I moved it up to 23'...
First grow, one of the plants has yellowish leaves, still green but a slight tint. The leaves are also curled down a bit. What could cause this other than overwatering as I don't think I am overwatering and other plants seem fine?
So most of my plants are doing fine. Looking good, a few spider mites here and there but they're under control, but lately just a few of our plants are having weird problems I cant seem to diagnose from the internet. Hoping someone can give me a hand! I think it's nutrients or PH but my mentor...
