Hi! I have the same thing in my garden I read about this treatment for white powdered mildew and it worked for me! Mix 1 teaspoon bicarbonate with 1 pint of water and water leaves that are affected. Hope it helps

A 10% solution of milk and water also helps with powdery mildew. It is used organically, how it works, I don't know, but it does.
