To solve powdery mildew use Serenade. Once you have signs showing on leaves the plant has been infected for a couple weeks and milk (?!?) is unlikely to penetrate into the plant I imagine, so while it might help the leaves like baking soda (changes the pH so mildew won't grow) your plant is still gonna taste a bit mildewy (unless you're allergic in which case it may be much worse). Get the concentrate and dilute it yourself to spray. Google serenade biofungicide. and +rep for Urine! Its sterile, so aside from the salt content piss is good -- beehives in India comes to mind also
