It is possible it is not budding, I have a haze cross that shows ass loads of pistil but is not flowering, I believe some strains just have more than others. I'm pretty certain mine is not an auto flower because it reacts the same way on my buddies gig that I got her from. Has reacted the same way through his 5 runs of her. It develops them early on in maturity and they remain that way throughout veg. When 12/12 starts it take about 2 wk or so to develop bud starts, which has way more pistils.
As far as the holding off a wk, I would prob 2wks because thats typical time span for recovery of many problems. A healthy plant you can expect to have a better if left to veg to full maturity. Not so much with one struggling with an issue, jump it to flower and it will spend some time and energies that would normally be dedicated to buds. Also, they usually will double in height in flower, at least in my exp. but many claim trip. Just saw ur pics after my slow typing submit, anyways..I concur with shake, it's not flowering, I can't even see the pistils showing their sex.
