Critical Jack Herrer AUTO.

Hi I'm a new member to this forum, and thought I would sign up because of the vast community for tips, ideas and also to meet new people.

Anywho I am currently doing my first own grow and I have a problem with a AUTO I have. It is supposed to flower after 15 - 20 days give or take, but what is concerning me is that I have had them in Flowering now for 2 - 2.5 weeks, and in total growing 6 weeks. And after this period of time even in 12/12, my other plants have started to flower and forming buds, but the AUTO is still now showing any sign of flowering.

Any ideas anyone would be a great hand, cheers.

What do you mean you have had them in flowering for 2 weeks and 6 weeks growing?
