In late flower, what to do. I've been doing some work on the room, which I probably should have waited but I didn't...so now I pay the price. I'm a few weeks to a month out. What should I do.

Never had it before....HELP

diluted vinegar. spray when lights out in the morning and then turn the fans on to dry it out before the lights get to it. neem oil works too. lowes has that. just follow the directions. wash your buds when you harvest if you spray oily things or really anything that doesnt evaporate ya know

id say get a microbe culture brewed for next grow. microbes will compete with the PM and starve it out or something. idk literally what is going on but it works and give your plants imunities to disease

I wouldn't spray neem on flowers. I would rather honestly smoke PM than neem. I like the PH change with the vinegar though, sounds legit.

3% store bought Hydrogen peroxide diluted in water. I've used 12-15 ml per gallon safely. Kills PM on contact. You can also buy GreenCure. Mix it with water at 1/2 strength. Organic and safe for flowering plants. Can also be harvested within an hour of spraying according to manufacturer though I wouldnt suggest it. Both methods will keep it at bay without leaving traces of smells or tastes, but wont be an absolute cure. Should be enough to keep it away until harvest though if you are diligent.

Google catalase positive. The organism bubbles thanks to catalase, an enzyme capable of outbreaking h2o2 into 2h2o +O2, Its nice because the chances of watching a pure o2 buble are very little But for the hobbist means two things. It can resist it and the overcome is guaranteed
As i can recall the catalase is one of the defense-attack mechanisms of oidium type molds. Also hipsters are catalase positive

I didnt tried the greencure but it looks aligned with that film-forming polymer products. I would include it in the oily type nuke classification

good luck and mind you cant spray your leaves in the next two runs [1st rule prevention]

Nothing oily about it. Its basically Potassium Bicarbonate.

hell, surfactants is what i meant. I judged it after seeing a leaf pic on amazon can u believe it? ^

Yeah it has potassium bicarbonate, diluted into water doesnt work for plain control. Anyway where the meat is is in the vehicle of the product, at least for fungicides.
