I'm into the 3rd wk of flowering and I noticed a fine, almost like baby powder substance on alot of the leaves. The humidity has been pretty high lately (got myself a dehumidifier) but what I'm wondering is if it is mold, is there something I can do for them or should I just keep the humidity down and wait? This is my 4rth grow but 1st time in Summer (humidity's been high outside too) Thanx for any advice
