I never had to deal with that stuff, so I'm not sure what to recommend, at that point in bloom. What i can suggest, is that you get some better air circulation in there, in addition to lowering humidity, if necessary. I like to keep the humidity at about 35% during bloom, and around 50% in veg, which works great. You have alot of leeway to work with when dealing with humidity, so don't panic if it's 25% in bloom, or 75% in veg, or something like that.lol As long as the temps are okay, the humidity will be okay too, as long as it's not
really extreme. Here's a good rule of thumb....the more humid it is, the more important your ventilation is, or you'll be risking molds/fungus/bud rot, etc....Of course, ventilation is
always important. But, it's just a tad more important when the humidity is high, or you have lots of damp soil or leaves in your room.
Edit: If you don't already have one, an oscillating fan is the way to go, IMO. They do the job much better than a stationary fan can do, in most setups.
