White spots on leaves

I've got a large-ish dinafem C+ that is about 2 weeks out from cut and today I noticed I've got white spots on my leaves..

Humidity in the room stays low-mid 30s and temps stay between 70 and 75 at all times with sufficient air flow..

This seems to be the only plant experiencing any problems.

Powdery mildew. Spray with diluted H2O2 or Green Cure every day until harvest, no problems.

cut it off ! get it out!! QUick many before it breeds!
