New grower here wondering what I should do about my constant battle with PM here in Michigan. I've been removing any leaves I see with it but it continues to come back. About a week ago I did a hydrogen peroxide/water mix and sprayed all of my plants but it didn't seem to do much. Should I continue spraying with H202 (wondering if this safe for buds if its on a cooler day with wind to dry quick) or should I just let it be and do a bud bath after harvest? Just worried since I have about 6 weeks left still to go and if I keep trimming at this rate I'll run out of leaf's lol.
This is an outside grow, plants are separated with with enough open space so they don't even come close to contacting each other and they have been defoliated extensively to try to combat this.
Side question- It got down to about 49 degrees last night, when I should really start to worry about temperature? I see a lot of MI growers here and if you're not harvesting until Sep/Oct how do you deal with the low temps?
Appreciate the insight.
