Mold? Fungus?

stoneyfisherman · Aug 23, 2021

I need some help here. We had a day of rain here in SoCal 2 days ago and I'm wondering if the moisture caused some mold or if this is fungus or what. I just noticed it on a couple spots on only 1 healthy lady. My butternut squash across the garden started to show some powdery mildew? I think. I have a 3 in 1 miticide, fungicide, pesticide concentrate being delivered today for the squash. Would that be safe to spray on my lady since she is in full flower mode? Any ideas as to what exactly it is? Thanks for any input.

That looks like PM on your cannabis. What spray did you get? Is it the organicide 3 in 1?

Powdery mildew I think. Cut them off and get some spray

Yea that's powdery mildew, easier to prevent than treat.

No need to cut off those leaves. There are a few sprays that can work in flower, mostly bacteria-based fungicides and potassium bicarbonate. Avoid ones with oils.

I alternate between Southern Ag's Garden Friendly Fungicide and Marrone's Regalia.

Garden Friendly is Bacillus amyloliquefaciens
Regalia is Reynoutria sachalinensis

Thanks guys. That plant is an unknown bagseed but I noticed a few small spots on 3 of my 5 trainwreck. Need to stop that shit before it gets out of control.
