Definite bugs, looks too big to be spider mites. A
Pyrethrin based fogger works well (flea bomb) and degrades quickly. If not too far into flowering, it will get rid of most bugs. There is also a mosquito coil that also contains pyrethins... they sell them for camping and stuff. Burning one with the fans off will dose the plants and everything else without leaving residue. I know there are some homemade pepper based recipes on here, but capsacin doesn't always break down and it can be very irritating if you don't get rid of any residue.
My last grow included some clones that someone gave me... it also included the spider mites that were living on them as well. It was difficult to get rid of them totally once they are established. I have learned to make sure all new plants go thru a de-bug process using a few different methods. It's a LOT easier to prevent them than to try to wipe them out.
