Question...I have Powdery mildew on a plant in flower,,,

This is one of the most low impact but most effective, I think…have put coco coir to use asap and when you let a bacteria kill another bacteria (Bacillus Subtilus promotes gut health I think… could be wrong, again lol) is genius!
This has been the worst year here for humidity and heat.

Cheers
Sparky
