yes it is ! good catch ! double check under the leaves with a microscope : your looking for tiny bugs. i'm guessing you've got something like spidermites, thrips, or white flies. What i've done against these is to use beneficial bacteria - they dont get rid of the bugs but they do do a fair bit of prevention. So combine these with something like sticky yellow tape. So you're looking for B.S. , B.T., maybe so others. just message me when you find out which pest it is I can tell you which of these beneficials you need 🚀
