I was checking trichs this evening, and happened to put the loupe on a big fan leaf, lo and behold there was a BUG. Can't see it with the naked eye, but they are little, bitty, teensy, weensy white bugs. I sprayed, hated to do it with all the nice buds, but I did it (used organic stuff). Any ideas what this is? should I worry? Are they aphids? they seem too small. Or am I just getting creeped out too easy?
