Looking over your couple diary entries, I don't think this plant ever revegged, it just took awhile to get it to flower. Revegging a plant takes several weeks and the new growth comes in VERY weird, like it doesn't even look like cannabis anymore for awhile. Usually single blade leaves that are real waxy looking. I'd just keep monitoring your trichomes and treat it normally. Auto genetics are finicky, not every plant is queen of the ball, moreso than photoperiods which USUALLY are a little more stable.
