Dear Jason,
This appears to be a Caterpillar eating a Marijuana Leaf.

Yeah I’ve seen plenty of caterpillars eating cannabis flowers… I did not realize they also ate/attacked leaves.
Thanks

    But what is making those caterpillars? Can it be those tiny little greyish brownish moths? How best to KILL ALL OF THEM in between rounds? (organically) BT does not work on these!!

    Thanks!

        Bt kills the larva, the bud worms, not the adult moth.
        It must be sprayed every week to 10 days to be effective, but I’ve had very good results with Bt on cannabis for years.
