I use Hydrogen peroxide for harvesting bud wash; 1 cup 3% per gallon H2O. Cut hangable branches, dunk and soak 10 min in the peroxide mix, remove, dip in second bucket w fresh H2O, remove, let drip, hang in well ventilated area w light air movement / circulation. 55%- 60rh ideal zone.
I’ve seen reports that the HOCL can be used also. It’s not one I have experience w, mostly due to access more than anything else. It’s not readily available to me.
The buds are contaminated, so ingest at your own risk. Personally, I toss that shit in the compost. 20 years ago, I tossed all my contaminated weed in the compost, and that’s where it ended. I went to buddy’s place to buy a sack of weed and he told me how to get rid of the mildew. Got rid of it and moved on. Learned a valuable lesson about bringing in clones from someone else. Have to decontaminate it first.
@catapult Thanks a lot for quick reply.
Yeah its same here. I just got back home after visiting 4 Pharmacies and Bauhaus they all don’t have it. Or if they have then its with NaCl.
Then as you do, I’ll also use Hydrogen Peroxide.
@JoeCrowe I really appreciate your point. But I have put so much effort and energy in growing them I dont want to waste them. They smell amazing and I don’t mind. I have smoked some crazily spiked and bad weed in past, now this is 100 time better than that. Also when we buy from a dealer what is the surety that it was never infected 
He was the one that told me how to get rid of it.
@JoeCrowe
Can you suggest any possible solution its not on all the buds yet, only on the bottom ones.
HydrogenPeroxide will atleast wash it off right?
I’ve never seen hydrogen peroxide have any effect on mildew, let alone washing it off.
Sorry for stretching it. I hope you understand by desperation. And I really value your experience 
What will you comment for Hypochlorous Acid? Or please suggest any anything except throwing them away.
PM is like that. From 1 spot on 1 plant to an entire tent in no time. Wherever it is it shouldn’t be cause it will infect others. Cut it out.

This is a good source for info about HOCL.
Post 4 shows a test someone did on PM. Good luck!
