Wish i was stoned! No job, will b tested. waiting til harvest. as a noob, having issues with posting...may be duped here. so, here is the status: 85 day/78 nite. plants at 5"/ 2 wks in. lst'ing them now. some showing blk/dark blotches on lower leaves, most likely over watering, right? Can't b nute issue, no nutes yet. I got c02 from your idea, 2 bottles. doesn't 2-120mm intakes blow out the c02? 1 yeast/3 scoops sugar, h20, lid w/hole, right? carbon filters impeding air flow/increase temp. there off right now. just 2 bright lites out of roof of tub

ambient room temp 78.
question- h20 tubes sticking out or taped to inside? temp at 85 too high? given co2 kind of available. FIM/Cropping??? Most importantly, 12/12hr to determine sex, then back to veg? I need to get down to 3, right? Many thanks for your time!
