is it growing new leaves or is stem elongation occuring? It will not be subtle if it re-veged. LEaves will grow super funkytoo -- like 1 or 2-fingers and no seration (smooth edges). Further into revege you'll see an absurd amount of branching, too.
if it did revege, i'd just watch the ripening and harvest what you can when it is ready. Might have something that looks like Dr Grinspoon strain. (basic image search can show examples)....
the existing flower should still ripen, at least. Buds might look like individaul calyxes spread out over a long stem, but it'll still smoke.
Hopefully, you are wrong about the re-vege mishap. Keep eye out for nanners/pollen sacs going forward.
