Being an auto, she should be flowering like crazy by now, but after looking at your diary, 2 things caught my attention. Chronic/severe defoliation can stop all processes and progress for up to two weeks each time it is done (didn't anyone tell you not to defoliate autos?) and secondly, after plants have been mega dosed with nitrogen to within an inch of their lives, this can cause such a toxic shock to the plants metabolism, that they will never flower, and yes, I am talking from experience.
The only thing you can really do is to put them in a 12/12 light schedule and see if that will encourage your zkittlez plant to flower. Another thing, seeing as there are no flowers yet, your plant should still be being fed with grow nutrients, (half strength is plenty strong enough) and save the flora nova bloom for when she is flowering, starting with the bloom formula when little "budlets" have formed.
Hope this helps,.... Organoman.
