nice looking ladies! As others have said, give em more time. I have never had a plant finish "on time." I already add two or three weeks because I am growing in 4 liter DWC tanks. And even then, its almost always at least two weeks more than that.
Case in point, today is day 90 for a strain called "Speed Bud." It was supposed to finish in 8 weeks. It is still easily two weeks out even now.
