I can't believe nobody has any input on these! These things are worse than spider mites and are probably just as common.

I'd you're get unexplained deficiency symptoms in early flower and your yield aren't quite up to par, then this could likely be the culprit (and it most certainly is if you're battling a so-called "fungus gnat" infestation that doesn't seem to respond to fungus gnat treatments).

Anyone who is getting clones from a dispensary should be especially wary. My bugs came from dispensary clones.
