Am in the midst of 4th legal grow...had usual problems (Bud Rot, yellow leaves, bugs) but never encountered this...First thought was Powdery Mildew...used 1 tbs Neem, baking soda, detergent...no luck...upped the ante to 2 1/2 tbs Neem, seemingly not working although doesn't seem to be spreading...How stubborn can this be to eliminate...Thanks in advance

Diluted peroxide has worked for me.

I'm newly growing again, but when I grew full time, I made a habit of adding two drops of bleach per five gallons of water, every other day. Iirc it was like 150ppm chlorine. You may want to use less on a foliar feed....

Maybe a peroxide spray, rinsed with chlorinated water?

I like chlorine in my grows, mainly did it for root rot prevention in the summer, but I'm sure it's fine for a foliar spray.

But I'm emphasizing that I ALWAYS added bleach. We're talking tap water amounts of chlorine... But it's enough to keep funk from growing for a few days.

My partner and I agreed it was probably our most useful "amendment". You can't run bennies, but I prefer to just keep it sterile.

Sometimes, you just can't wipe down after making a mess. Sterile water is your friend imho.

I would be curious as to the relative humidity in your room, or whether you are doing unnecessary foliar sprays which are causing the mildew.
