The plants in the cups sure look patient. They’re looking top notch. How far along are the flowering plants with the PM? Man. if you can, you gotta nip it in the bud (heh) right away. It ruined my whole harvest because I was so tight on cash. I don’t ever want that stuff to get that far again. And it didn’t even look like it was real bad.
If they’re young in flower may be able to use a sulfur product. Sulfur powder a few times seem to kill it off. There’s a thread from somebody, and @JoeCrowe seems to have a system of killing it off completely.
Has anyone here defeated powdery mildew?.
You can still get a handle on the veg tent. I used Safer brand (sulfur fungicide or something? ) a few different times and it killed it in the house. Oh man, try and get on it. You will be so sad like I was. Good luck!
