Ok I'll post a pic sometime tomorrow thanks for your help I was also thinking could it be high humidity ? The room goes from 55-70 sometimes and the pots rarely dry out

70% rh is not good. Pots never getting dry another problem maybe u just point pinned ur problem, get some good ventilation going in ur grow room, wait some more in between watering. best of luck!!

with dark green leaves and dying leaf tips, it looks like over fert combined with over water if the coco isn't drying out. the hard part with photos is it can difficult to determine leaf color, which is really important to determining the problem. we need pics that show leaf color as accurate as possible. birdie mcbride mentioned using f&d but that might not be a good comparison. don't understand what the person was trying to say, unless they use coco as the substrate.

Coco is considered hydro. The plant feeds from the water source, not soil. Check the ph charts for hydro not soil.
