HELP NEEDED - Best treatment for powdery mildew

One of my girls has a case of powdery mildew and I've used several methods on my other garden to treat other cases and haven't had the best success. (Milk, baking soda and herbal tea with garlic and soap) Although I'm willing to try anything if it means saving my female.

Just wanting to know the best organic treatment I can use to get rid of it before the spores spread to neighbouring plants.

This plants strain is green crack god and it's in flower and buds are growing. Don't want to have the growth slow. Growing outdoors but have had the plants under cover as we have had non stop rain for almost a week.

Please help!

I rotate a spray of diluted h2o2 one day, Green Cure the next, Actinovate the third day. Repeat every time it comes back, you'll be clean at harvest. All organic and safe methods that will not foul your buds. Good luck!
