@Beerhunter CDN It is your call dude. If you knock her back to 18/6 that should speed here up a little but it won't wave a magic wand. I think you are probably right on the flowering time. She is clearly very happy and is definitely in flower, but is just taking her sweet damn time. Please dont kill her off as she is going to be a monster that will give a great yield IF you are happy to give her the time.
If you knock her back to 12/12 now you may risk shocking her and doing more damage, so i guess you could bring the lights down slowly but unfortunately that is all i can offer right now.
