Can you get a photo of leaf damage and/or the underside of the leaves? To me they look like a spider mite species but I don't see webbing that typically forms on the underside of the leaves. Alternatively, do they scrape off easily or adhere to the surface?

Regardless of the species you need to clean the leaves. Wipe both sides down with a paper towel covered in dish soap, ideally spray the whole thing with neem oil.
