Powder Mildew

I have a quick question that hopefully someone can help me with. I usually dont have a problem with mold or mildew but in my last 2 grow cycles I have had a huge problem with powder mildew. I had to kill more than half my plants from my last grow, and on my current grow its light as of now but I can see it start to become heavy. I've tried everything running more fans in the room, opening windows, and even made a foliar spray composed of baking soda, dish soap, and water in hopes of stopping it but nothing works completely. Any suggestions from anyone out there who has experienced this problem? Thanks in advance

neem oil and green cure. you can keep it at bay a bit, but you have to spray weekly.

or start fresh from seed like I did

SULFUR BURNER. keep that shit on deck at all times. and lower your humidity. If i see any pm or i think its coming on, ill run the sulfur for about an hour when the lights are off. it smells like SHIT, but it work. i use a ozone generator instead of a carbon filter as well, i hear that helps with pm or mold issues but im not 100% on that

Whats your RH? 25% milk misting when its down say 35% RH.

oh and wipe the room down with bleach water and bomb before your next grow.
