not sure but my first guess is spider mites u look on the bottom of leaves to see if u see any? also u see any webs? u would have webs intill u had alot of then but check underside of leaves for brown or white spots i am willing to bet its spider mite and if so better act fast
Look all over and under a leaf with a minimum 10x loupe or magnifying glass - for a tiny white-ish bug, it's tiny, but it's elongated and not short and stout like a spider mite, I have the same symptoms on my plants, and I am hoping you have the same bug. Then hopefully we can identify it.
