Autofem????

I have grown some Dinafen Haze Auto in my conservatory since Feb. They are now 14 weeks old and seem to be stuck at the pre-flowering stage. They have appeared to be just about to flower for about a month and as these should only take around 10 weeks start to finish, something is obviously wrong. Any ideas?

wow thats noooo good..Im doing 6 of them and there rocking about 7-10days from starting to flower...Day 17 from seed mine r 7-9inches and 3to4 sets of leaves and more forming daily..What light scheduale r u using ???

I would throw them out and start a new.
