Powdery Mildew On Buds

Powdery mildew came back. It seemed to go away with some neem oil when it was in veg. Now it appears to have came back on my buds. What should i do??? Is it to late to save them?? Is it safe to spray neem during flower? I have exhaust fan on hi with my bottom vents open in my grow tent

.

Dr Zymes Eliminator may save them, it can be sprayed right up to harvest. $13 a litre to try it out.

An AirROS machine is a reactive oxygen species generator and it would kill off all PM and Spores. Expensive and worth it.

After this harvest you'll want to do a Sulfur burn in your tent, to sterilize all the surfaces against PM.

Good luck.
