yeah try to wait at least a week and than the harvest "window" should be starting to open but I think at least 2 weeks if you want a nice yield. That's going to shrink big time if you chop now, you'll notice it'll start to look really swollen and the buds will be come rock hard and the Calyx's will basically pop out and up. It'll look swollen and ready, not there yet dude. Good job though!
