Tried plucking leaves made way worse tried spraying with rubbing alcohol didn’t do much now trying 3% hydrogen peroxide 3 Tbs in a litre looks like it takes it right off any advice?
Also week 8 into flower I seen on YouTube you can bud wash as well before curing anyone try this? Any cons?

Welcome to RIU!

What is it you're trying to fix by pruning leaves, and spraying alcohol and peroxide?

You haven't stated a problem.

I've tried baking soda solutions on pm on plants other than cannabis, and it kills it. Haven't tried hydrogen peroxide but I've heard of that remedy as well. You've got to make sure the underlying causes are resolved as well, so reasonable relative humidity without a big temp swing when the lights go out, good air flow, good plant health, etc. Otherwise, you're just holding back the tide with a broom.

ya thanks makes sense but idk how I got it I have a online exhaust fan and 2 isolating fans for just 5 plants and right now it’s -30 so I have trouble keeping the R/H above 25%lol but i do have it around 72 degrees at night and around 78 at day trying for some nice colors maybe I’ll stop that

Oh, I missed that. I would only bother with any of what I suggested if you had mildew on your leaves. If it's in a bud, I think the mildew wins that.

Yeah, I'm trying to be gentle about this, but by the time you see the mildew inside a bud the battle's been decided. That flower is already dead, and it will only serve as a spore incubator for your grow. Your options are down to removing the bud from the plant or removing the plant entirely.
I'm sorry, friend.

Fix your air moment and or ventilation issue and the h202 will do the trick. Bump up the ratio though, I eyeball my ratio anymore, but I'm using twice that at least. It's my go to anymore if I spot pm, it can be sprayed in flower too.
