So, it reveged. whether or not it'll grow enough to produce a good enough "2nd" harvest is the question. The single-bladed leaves, if any are missing teh normal serated tips etc are the signs of re-vege. As long as it has enough time to reset, it should do okay. Nothing is in your control in that regard, so enjoy the ride.
it's an autoflower, so length of darkness is irrelevant.
