That sounds pretty normal for me and my usual crop of AK-47, and most other stuff I've grown. I'm not far behind you and I don't really smell them until I start getting my hands into them. That's the ladies trying to spread their love juice around in hopes of getting it inseminated. Sometimes even right up until harvest they don't smell much. Other times, watch out boy, get a carbon scrubber or six. You're what? About half way there? Yeah I'll bet in two or three weeks your going to start noticing them pretty well. The closer to harvest, the more trichomes, the more smell.

mmmm, love juice.
