Any experience with safer brand garden fungicide? (powder mildew)

Anyways so looked high and low for some green cure and well its nowhere to be found, anyways hydro store recommended this safer brand and I was wondering any experiences? Store told me to spot treat, others say drench? Also a few plants are on day 39/40 so are those safe to spot spray?

Safer is good. Spot spray won't do much. You need to treat the whole plant. And let dry with lights off.

With lights off, so spray move in fans and quick dry? And my veg is 24/0

You will need to turn lights off for a hour. It won't hurt anything. But spraying under lights will.

So even douse theflowering plants too

If you have to yes. If they don't have the pm I wouldn't. But yes safer is OK on the buds. Just don't get then super wet. You can make mold or bud rot.

Well they have spots would milk be better on the flowers or possibly h2o2 bath after pulling

Spray now. You have about 20 days right? So you would be fine. Also PM wash works good after you pull them if needed. Cut and trim. Let sit in the wash for a min then hang to dry.

Ya 20 days ill spray before lights go off and fans on high

Testing on veg first

mix skim fat free milk with water 1/10th milk to 9/10 water...mist plants...the change in ph will kill it...reduce your rh to prevent recurrence

Baking soda and water I hear works, I use General hydroponics pH+ and RO water, Floral spray with pH of 7.2-7.5. Powdery mildew is a fungal disease that favors acidic environments.

so a few of them got pm again in small blotches, about to treat them again, god damn powder shit!

So one application seems to have taken care of it then I brought in a new clone and now I know quarantine the new bitches, treat em and then place into veg! (ah atleast I learned something eh?)

great thread thank you
