Nasty lil fuckers they will stunt ur growth hard to get rid of. Safers soap works, maybe try just soap and water. With this you need to apply many times, but is harmless to plant. Wash out ur grow area. I've tried diatimatious earth don't know if it worked. I've tried neem oil only spray in vedge some people speak lowly of this stuff but after you spray it seems to act as folier feeding the plant seems to like it. Up to you what u do good luck.
