dealing with the caterpillars and also not sure weather to spray at this point. just got the bt and a cheap sprayer, but I'm in denial because I think I'm spotting them all. but when I inspect the rotten spots - as you describe with the jewelers loupe, I spot the tiny fuckers. last yr. when I hung to dry, the tiny caterpillars rappelled on silk from my hanging buds. I have some beauties in the flushing stage right now, and even my (non interested) better half is telling me I should spray based on the "if you see one, there's probably hundreds" theory. I have been pulling off about 2 affected buds each day. the bt stuff is safe to spray up till a few days prior to harvest but still I'm not sure I want it on my smoke. ALTHOUGH, I am looking into washing my buds for the first time and not sure weather to go with a hydrogen peroxide bath, or a baking soda and lemon juice bath. lots of related info on youtube and this site. one of my first posts. I wish good luck to anybody growing outdoors this time of yr.
