What are these light specks on the leaves?

Thanks Nova you are totally right Thrips was the problem all along, very well spotted.😇.

Hi there Beastmaster. Usually little spots like that are because of calcium deficiency. But if that's the case they're usually rust colored. what i'm seeing here is a slight pest problem, possibly even spider mites. That's because the spots are white-ish, and their edges are sharp, like bite marks sometimes. Check the bottom of your leafs for really microscopic dots. if that's the case try using bacilus thuriengiensis , available at any garden store. These are nematodes that parasite adults as well as larvae and eggs to control and maybe even fix the outbreak completely. Just follow the instructions on the package you get , usually you combine it in the feed as well as a spray, spray a bit less than an hour before lights off for the best results. Hope this helps ! 🚀

There are no pests that I can see, and no mottling on underside of leaves.
