Howdy fella1415, I'm not sure, but I think that it is a Thrip, but I could be wrong (will not be the first time, LOL). I had something very similar on my grow before last. I used Azamax directly in the reservoir (10ml in six gallons) and applied it directly on the plants as a foliar spray (as per bottle directions). This did clear up the infestation, and I had no further problems with them.
Good luck with Your grow.
