Or some sort of gene that just develops its power over time. All we really know is that females develop faster than males. Which would explain why Marie, Kelly, and Trubel all developed at some time for sure before the age of 21, while Nick (Five years/seasons ago) was 28.

I just realized how long its been since the beginning of the show.

Memories.
