Please see photo below (edit: added one above now). I've looked everywhere but have no clear definition as to what this is. The older leaves (on the right) has yellowish tint on the inside of the leaf. The one on the left has gold-ish specs (they look white but are indeed gold) all over the surface with some necrosis developing on the outer edges. I don't think it's disease but some nutrient issue. I don't see insects or mites. The cherry is not outputting many tomatoes either and this gold-ish speckled tint seems to be all over the upper part of the plant, including the branches. Any ideas?
