Morning StBuds, if your after larger buds, if they are still swelling up they are still growing an they aren't ready to be harvested yet, that's why you don't get in any hurry with them, the last 2-3 weeks is when they get huge. I'd wait to see some amber before you start to flush, by then they will be much larger an harder. Good Luck with them,but they will get lots larger if you wait a bit.
