WTF bugs maybe?

Check it out. Pretty weird looking. I have figured a lot of shit out but this looks beyond me. Help! I know i had some fungus nats, but I killed all those bastards recently. I got one of those no pest strips. Maybe there not all dead yet. My other question is, the bud in the pic is about the middle of the road as far as being finished compared to other buds, how far off does it look to you? Should I harvest early if the problem gets worse. Right now i find 3 or 4 leaves that look like that a day, all on the bottom of the plant. All the buds look fine, just shade leaves are affected. Thank you in advance. Man, I thought i was doing really good, and i still do, but hindsight is 20/20 and i could have done a lot better.
