If you haven't interrupted their long-dark cycle, all is well.
Leaves pop without serations and 2-3 fingers etc.. excessive branching occurs... it's really hard to not recognize a re-vege - it's got incredibly obvious behaviour. You are probably fine.
Even 13/11 is safe, but stick to 12/12 to be safe. 11:30 light / 12:30 dark is fine to dial in DLI, but not necessary to avoid re-vege. 10 hours of darkness is enough for 50-60% of plants. there is variety, but 12 hours is sufficient to cover all the variations.
