URGENT HELP - Powder Mildew week before harvest

Hi Guys

I have just noticed a fair bit of powder mildew on my crop. I am into my 9th week of flower, was hoping to flush on Tuesday.

I’ve been advised to start flush now and harvest on Tuesday (finish one week early).

I have done lots of research and read/watched a lot on washing them and hanging to dry. It really does worry me to do this as never done before and I’m in a really tight space and don’t want any smell to escape the room.

I’ve attached some photos/videos.

Anybody have any experience / knowledge to share having had this so close to harvest. Really worried I’m going to ruin the crop and was hoping for a great yield.

Really appreciate any help!!!!

Cheers
Steve

The second photo is the very worse one

Anything guys??

I think I would try Harvesting early, maybe wet trimming the pm spots, and drying in the dark.

Honestly it doesnt seem like alot I've dealt with worse before; I just put it in a tub with h2o2 and water and rinsed it and basically hosed it down; surprisingly I smelt the buds way more doing it that way lol

Defoliate, get rid of all the leafs you can to help with airflow and RH%.

Spray with a potassium bicarbonate or baking soda solution pH'd 11 - 11.5, this will make things alkaline and stop PM growth and can be washed off later at harvest when you budwash.

Keep the RH% below 50 but not below 40. Keep good air circulation. Don't let temps drop when lights go out, thats a double whammy as when temps drop, given the same absolute RH% the relative RH% rises dramatically and the dehumidifier pulls less water at cooler temps (double whammy). So keep the lights out temps from dropping.

That’s not to bad. Follow Renfro’s advice and you’ll be fine.

Just a heads up.
Bud washing does not necessarily make PM covered buds safe to smoke. It may neutralize the PM but from what I understand it is now within the plant cells.

My recommendation is to toss any clearly affected plant material then do a bud wash as a precaution for the remaining not clearly affected plant material.

Sux but it happens.
Good luck
