got wpm mid flower on 1 plant and late flower on another. Temps are getting really cold at night so the dew is getting them good. Need advice should I just scrap the plant in mid harvest and harvest the late one or wait it out? I sprayed sulpher spray a day before the pics were taken seems to have gotten more white.

What a disaster. Can this be salvaged?

Remove any leaves that are too damaged. Move to shaded area or wait till late evening. Wipe off as much mildew as you can with a wet cloth... top to bottom. Blast plant with water. All angles... tops... bottoms... everywhere. If you have any pests, now would be a good time to spray every inch with insecticidal soap or dawn dish soap and water. If you sprayed with soap, rinse after 1 hour. Then spray with neem oil and water or azamax and water (I like to add some potassium silicate for an emulsifier). Repeat every 5 days or as necessary up to 2 weeks before harvest.
​
There are lots of "solutions" for this, the above it what's worked for me in the past. I never had a WPM infection that was too bad to control though so I never had to go nuclear.

Increase air flow to your plants. Remove dead/damaged plant material, clear out some of the inside leaves, remove leaves that are touching too much.

WPM is in your plant now, so from my experience it will come back if your airflow/condensation isn't in check.

Ok so I noticed everywhere I sprayed looks white now.... I sprayed it with 12% sulfer at a 35ml to one gal water mixture. The white spots don’t look like powder mildew more like a residue. What are the chances it’s just the sulpher on my leaves? As u can see from the pic there is just little spots now before leaves were covered. So Wierd

I've heard sulfur works well on PM, but I've yet to see it. My dad burned it when he grew indoors and it sure got rid of his thrips, but he never could get the PM under control. Burning is more effective than spraying.

Still looks like PM to me. Wipe it off. If it comes back you know what it is.

Rinse the sulfur off and spray with sodium bicarbonate. You can add a little olive oil (or any vegetable oil), and maybe a bit of dish soap (I use safer's insecticidal soap, but it has a bit of a smell too), or you can get something like Green Cure.
Took care of my powdery mildew, and I'm using it as a preventive for botrytis on the recommendation of a grower in my region.
You can also do what Jorge Cervantes does and wash your buds at harvest, especially if you want to keep using sulfur.

I bought potassium bicarbonate, the guy near me who bought Green Cure got it from the american amazon. I can see how it looks like I said I used Green Cure though. Potassium bicarbonate is the active ingredient in Green Cure, like 85% or something. I got it on amazon.ca.
If you use either of them at full strength they will turn your pistils brown, but new ones will still be white. I use it at half to a quarter strength, and my pistils seem to be fine.
After looking it up, I'm not sure if the sulfur will wash off, as it's listed as insoluble in water. I also don't know how it might react with potassium bicarbonate, I'm not a chemist lol.

God I hate pm... I just found one of my outdoor plants is covered with it. A week before harvest.

I’ve tried treating it in the past but there’s always a lingering doubt that ruins the experience. You have to cut your losses when it comes to pm.
