Unopened calyx's?

Hey guys! Plant has been in flower for approximately 4-7 weeks, haven't really been keeping tabs. Well my problem is that there's a decent amount of calyx's which remain unopened. I did remove some fan leaves prematurely, could this be the cause? Or will they still open later? Cheers for any help!

Looks like 4 or 5 weeks to me. They will continue to swell and develop until harvest. It's very important to keep track of flowering, find out exactly where you are. Don't remove fan leaves unless they are 70% yellow or more.

This is the plant here:

It's just that section of the cola that hasn't filled out?
