Ahhhhhhh.....ya I may have boosted my nutes for the last feed..other then that my girls are looking really nice I'll post a pic of them and the nutes I'm using....

They look great!
I think I'll stick with my first impression. You pushed them about as hard as possible. I'd back off on the feeding, but don't see any problems.
