Yeah your probably around week 6 or so of flowering at the most, they look sick though bro. Try and wait at least 2-3 more weeks minimum, do your best to hold off on them, because the last week or two they start to really swell and fill in more than you can even see happening. That's how you get the weight and density right now if you pull those, they'll be small cola's when dry and very fluffy/airy IMO. Wait and you'll almost double your wait come October. No point in harvesting now, your way ahead of the game for the majority of us in the flowering stage at this point I think. So good job Man, and I hope you enjoy your hard work.
