How big are your plants.........If there reasonable size take a bottle of ivery dish detergent 2tsp per pint of water and spray your plants. Spray the undersides and rub the leaves. killing anything on the leave....rinse the plant off afterwards and then put a good coating on and leave it overnight. Try not to do while the lights on cause it isn't good for it. You can with low levels of light but if your using a 400 or bigger i wouldn't not during flowering anyways. Go in your attic and look around for a few ladybugs. I keep those little jumpimg spiders in there also.......
