Powdery mildew and need 2 more weeks

I found some PM on my sativa plant. This plant need to go for another 2 or 3 more weeks. Would you recommend cutting it early and wash with peroxide, or should I keep growing it and just keep spraying with peroxide, and then give it a good wash in 2 weeks. My question is will that white stuff come off the buds after washing in peroxide? Anyone had this problem?

Recommend to do a peroxide wash, and continue up to harvest, and another after you chop.

Is spraying with peroxide effective?

It kills the wpm, but doesn’t prevent it.
