I am on my 3rd run of Hso blue dream I get to 55-60 days of flower and the Colas always start to mold I have a dehumidifier and a large fan with exhaust what in the hell do I do every run has had it happen.
The oscillating part broke but I have a large fan moving air 24/7 I set my dehumidifier to 45% rh it fluctuates to like 55 rh briefly
Reduce water and Rh in your grow give them minimum water use neem oil 1x time per week neem oil has its flavor that should be gone by harvest if really bad dip ur plants into a bath of warm water and 10% bleach allow to dry under a warm wind in fan for 6-8 hours good luck
