Is this plant revegging?

I was running this blue mammoth auto that wouldn't trigger under regular light but then I put it into flower lighting for a couple weeks, had to move it to clear some room and put it back under a different light but longer hours (16 instead of 12). Now, Ive grown other autos where Ive had to trigger them with 12 hours of light in order to get the flowering going but upon increasing the hours of light, they finished anyway. I'm seeing what looks like new growth near the top of these bud sites which I'd estimate got to about week 4 of flower and then reverted back to veg.

Got a better colored shot

I really don't know what autos look like when they reveg. With photo-period plants, the leaves lose their serrations and you get single leaves.

It did reveg, so much for "autos" that don't auto. I had to trigger and finish it under 12/12 lighting and the plant had all kinds of issues with nutrient absorption. Lucky the thing finished at all. The bud was nothing special in terms of looks but it actually smokes nicely and gives a relaxing sedative feel.

Seems to me, if you have to trigger with the photo period, then it's not an auto.
