Peroxide to kill powdery mildew in flower?

I’ve read a bunch of different percentages to spray on my plants that’s are in flower. I’m using 3% solution from the store. I’ve read 9 parts water with 1 part peroxide (h202) or 5 to 1. How many days should I spray it? I don’t have much just trying to get this harvest to completion. About 6 week in flower.

Use powdered sulphur at 1 tbs per liter spray and repeat a week later

Check out zerotol its a peroxide product you can spray all the way through flower

Sulpher will kill it like @sdd420 said. This crap will keep it gone for next to nothing.

It does, you have to continually shake it while spraying. It leaves a dusting of sulpher, so only in veg. The arber is safe all the way through flower and knocks it right out.

I know this wasn't directed at me, but my tea bag label told me today again that free thinkers never charge for advice. Thank you Salada tea

You might also try bicarbonate of soda mixed with a little dishwashing soap.
