Powdery Mildew is this it? Or is it wet powder from the plastic on the tent

does this look like powdery mildew. I think its the powder that coats the inside of the plastic on my outdoor greenhouse. looks like water droplets in the powder.

If it rinses off with water it’s not WPM. If you hit it with peroxide and it DOES rinse then; it is. More than likely.

thank you @Myfriendis410
what could I use to kill and prevent it from returning?

ran water over a leave and it appears the white came off

Watch this short clip:

Mild peroxide and water solution sprayed periodically will keep in check.

A couple of tablespoons in a quart sprayer is all you need.
