For the most part it looks like normal die-off of older fans in the 3rd week or so of flower. Some of that almost looks like insects (mites): make sure you don’t have an infestation. Do a close inspection of undersides of leaves near the stem with a loupe.

I see no bugs at all. I dumped other plants and just focusing on these. They still have the spots. Should I clip older bigger damaged ones?
