Cream Caramel Auto

Not exactly sure what's going on. I was going to chop last week but then some calyx swelling started happening. (Not sure if I'm phrasing that properly). And the buds just started exploding with growth. Not sure if that could be from 12/12 to 18/6 and then back to 12/12 or if that's just the nature of this plant. I've never had an auto be affected by light cycle before, so I would be surprised if that was it.
