I broke down and activated the exhaust fan. 85% humidity overnight simply won't do now that they are in flower. However the exhaust fan is on a timer; turns on for an hour every three hours. Hope that's enough. During the day, I open up the top flap of the tent. Ventilator fans, one fixed, one oscillating are on 24/7.
Dimmer now up to 100% and I still selectively and carefully remove leaves that block light from the buds now cropping up all over the place.
@Grow_for_Happiness, Looks hopeful--I did a quick wet trim after leaving them hang for a day. No mold issues. Another day or two before a final trim and jarring them up.
