Yeah it's whitefly, I probably should spray them but with me being so close to harvest I'm not sure I should due to getting mold and mildew problems . Maybe the best thing to do at this point is just get some fly traps and drench the soil with some gnatoff. I'll spray my veg room though, just to be on the safe side.Google "Whitefly on cannabis" and see if that's the bug you have. Then look up the treatment or come back and ask.
It's definitely whitefly, need to act quick and get to the hydro store in the morning.could be mealy bugs look them both up
