I have one plant that has been drooping recently, not just in the hours before/after lights on. I am growing in Fox Farms ocean forest and my temps are between 77-82 with lights on about 35-40% rh. I have been feeding MegaCrop at about 2.5 g/gallon about every watering. I am guessing my tap water is bad even after 24-48 hr aeration causing the beginning of lockout of something. Went in today and saw a yellow splotch on a single fan leaf. I guess im asking what lockout do you guys think is starting? I will be switching to RO water tomorrow for sure!
