    Been having water sit on outdoor plants in the morning till sun reaches them. It’s causing these white spots. Any idea if it’s PM or just residue? OG strain. Cali

    Powdery Mildew looks like fuzz.

    It doesn't hurt to preventively spray against it every week.
    Potassium Bicarbonate
    or Sodium Bicarbonate = Baking Soda
    1 tablespoon per gallon of water.

    This raises the water PH high enough to kill the mildew and has zero effect on the plant.
