These white spots on my plants have been appearing on my plants for the past couple of weeks. It almost looks like white/silvery paint was splashed on them. I thought it might be bird poop at first, but i don't think it is anymore. Ive been spraying them with hydrogen peroxide and wiping with a paper towel, but they keep appearing? Does anyone have any idea what it is? I've seen white powdery mildew on other plants before and this looks different (less powdery).
