First of all, you shouldn't need to transplant. That container is plenty big enough to finish off a single flowering plant. Secondly, congrats on just about completing your first grow with some consumable product to show for it! :jointsmile: (That's not something that everybody is able to do.) Other than that, don't skimp on the drying & curing and enjoy it when it's time.

Most of the yellowing you see is normal and usually isn't a problem in flowering, but you'll still want to stop using nutrients at least a week or two before you chop it down and make sure to flush the soil really well. Next time, I'd get in the habit of monitoring your pH frequently. If it gets too far out of whack, you'll end up sacrificing yield every time.
