The insects in your first pic are spider mites. The loopy tracks in the next are leaf miners. Minute Pirate Bug (Orius Insidiosis) is a thrip, whitefly and mite predator that works, especially for thrips and whitefly. I routinely use them to clean up thrip infestations in my research greenhouse. See: Arbico Organics. If you have 2-spotted spider mite, ugh. For an indoor grow you need to instill "greenhouse rules". Filter air going in, never go in with clothing exposed to your garden or yard, and wash/sterilize all pots, implements, etc. that you use in there. Use good soil. No half-assed crap from the hardware store. Commercial soil can carry many diseases and predators. I would nuke that grow room thoroughly and start over clean. Just my 2 cents. Good luck man.
Chromophore Reviewed by Chromophore on . Mites...two wks to harvest. Please help. This is my first indoor grow, a whole new experience because I've always grown my medicinal cannabis outside. I am 2 1/2 wks from harvest and everything in the flower room is infested with spider mites. The mites have black bodies, I've never seen anything like them, am I correct in assuming they are mites? I have 4 Jack Herer, 2 THC Bomb, 2 1/2 wks from harvest, I also have 2 Love Potion and 1 Cotton candy with 4wks to go. I've tried everything to beat the mites, insecticidal soap sprays, Rating: 5
