Thanks for the insight everyone. I decided to kill off 2 of my perpetual plants that still had 6 weeks of flower left as they were getting bad compared to the ones that only have 2 weeks left to go. Will just ride it out with those ones. As for my veg and mother room I decided to spray e erything with a copper based fungicide called End-All 3in1. I sprayed everything until it was dripping. I also ordered Rhino Skin from advanced nutes, apparently it's a silica based product that helps defend again PM.

Hear more and more about silica fortifying epidermal......... SiO2 I'm assuming .......an oxide?

So for the last 6 months I've been battling PM issues. Dont seen anything during veg, then by 2nd week of flower it starts and get progressively worse.

Room temps during the day are 25C-28C and night time temps are probably around 18C-22C

Humidity is around 45%-55%

210 cfm intake, 2 oscillating fans and 400cfm fan/filter exhausted through 2 hoods.

I started using a dehumidifier around 6 months ago as well. In wondering if the dehumidifier is what's causing my issues by spreading the spores?

I've done everything to get rid of it, completely cleaned, painted and bleached everything in grow room after harvest, spray plants with Milk/water and also End All fungicide (just started that one) and it still comes back. I just sprayed the plants 2 days ago and I can see PM growing everywhere regardless.. I'm about ready to cut everything down and call it quits. This is super frustrating. And I have been throwing for 10 years with out this issue.

What's your thoughts?

PM can’t survive in temperatures over 88% F. I also had a long bout with PM which I was finally able to conquer using heat alone, as in 90 degree lights-on temps and only letting it drop to 87 at night, combined with a powerful dehumidifier equipped with a MERV 13 filter. This only works with heat tolerant strains. But it shuts it down.

Good luck! Don’t forget. Once you have it it’s always there. Despite any temp bandage you apply. Or what preventative spray claims.

New genetics... clean room. Once your at a spot to do A fresh start I sure would be planning that.

My place is surrounded by PM. The grass is infested. One day I accidentally stepped on a patch of affected PM grass and saw the *poof* of spores. The sight was surreal.

The air we are in is packed with impurities that we just don't see.
