Hi have this autoflower that I think is getting close to harvest. Just wondering if anyone knows what the spots could be from, how to treat and if it’s worth plucking all of them now. I had a mite problem a couple weeks back but I thought it was under control. Have been using peroxide 1:1. Once a week.
Yellow and brown spots.

It’s really hard to see exactly what that is on those pictures. It, unfortunately, looks like powdery mildew, but I can’t be sure, do the “spots” rub off?
That was a bad pic sorry didn’t notice. I was speaking of the yellow and brown spots. The white was there because I had just sprayed hydrogen peroxide mix right before the pic. I’ll post a better one

OK, in the second photo I see what you mean. It could be a lot of different things. My first thought would be calmag or P/K deficiency. In any case it doesn’t look too bad, maybe up your calmag. I think I’d try that first rather than make any drastic changes. I will say that you’ve got at least a couple of three-weeks to go.
Thanks for the input will give it a try
