Is this powdery mildew?

Hello RIU.

Found this signs on a few of my plants: some of them were clones that i tossed out because they came from a weak mother than after taking the cuttings, started with mildew problems.

But the plant i took this leave from, is not a clone, it's from seed, and another strain.

I take precautions when going to my indoor, but since i had mildew last outdoor season, guess i carried some spores everywhere i went.

Yup. Mix 30% milk with 70% water in a gallon n spray everything. Leave it dry for a couple days at least. It’ll rinse clean when and if you decide to rinse it. And do it once every couple weeks to keep molds at bay. You can spray plants room and all. Outside or inside. It’s a agricultural remedy. It’s how they keep the veggies we eat good.
