For real powdery mildew, you can use baking soda or sodium bicarbonate, absolutely safe, cheap, and you can also spray it on the buds. In my Greenhouse Grow week 20, you can see the sodium bicarbonate and the treatment of the Runtz, including photos the next day, no more mildew. Sodium bicarbonate creates very unfavorable growth conditions for the mildew, it just disappears 👍😎
