Are my budds ready for harvest?

NO! A few more weeks it looks like. See all the new pistils? Buy a cheap illuminated 30X jewelers loupe. Check Harbor Freight. Or a big magnifying glass. Check your trichomes, not a calender or advice from afar. But +rep for just getting them that big without knowing everything. Good on ya!

The wait (and the magnifying glass or loupe) will be worth it come winter and you're kicked back toking the good stuff!

Listen to Hotrod, get a 30x mag glass. The only method I use is to monitor the trich's. Everybody prefers a different smoke/high. There are endless threads on this subject. Good luck.

not even close. GL

I would guess, at least three more weeks!

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.

thanks for all the help guys!
