An update, I left the camera back in the room and I'm too exhausted to get it but I can sum up the pics - things look worse. NOw, the two big strong chocolopes are clawing up, and several of the plants had powdery mildew on some lower branches. I really wish I would have not been so greedy and chopped all the lower branches off. Is it too late no that they're four days into flower?
I tested the soil ph in several of the pots using that test kit above and all registered about 7 - my water / feed has been 6.5 for a while (definitely since they've been repotted.)
The RH (lights on) is 50-55 Im sure the extra six hours of dark right after watering didnt help with the mildew. Does anyone think that this clawing could just be overwatering and will pass? I've got the exhaust cranked up, the two clip on fans and a small fan pushing up from the floor. I wish they had a soil dehumidifier!
**** edit *****
alright so, I put the ladder and rope away and got my wits about me (the camera was on the table behind me). I pulled off some more of the low hanging fan leaves that had mildew on them and sprayed the rest of the lower stuff and soil surface with serenade. The top of the soil was actually drying and cultivated easily. Still looking for experience based advise on chopping the lower growth - at the begining it seemed like a cool idea to have it as low as possible for stability???
tom - on the air movement, You're right and when I switch out the bulbs I will do that - but you also have to remember that the line has an 8" max fan at the end (over 400cfm) and a 6" can fan pulling through the filter and into the lights (250 cfm) so that's not a big issue - but I am having a hard time trying to figure out how to have something blowing through the bottoms with all that growth, she air king clip ons move the tops around really well.
