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

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

what is the dilution ration for water to peroxide ?
A couple of tablespoons in a quart sprayer is all you need.
