First Colubrid... Question

So we picked up our first colubrid today. A lavender Cal. King. The seller said it was part of a "breeding trio" blah blah blah. He was pushing me to buy all three but I got out with just this one that is supposedly a female. I really don't care as I will not breed. My question is, do you guys have any idea how old she might be? I wasn't sure if this snake had already bred or if it was part of his plan or if he was just a snake pusher. Any idea?

Here is a picture with my keys as a reference size

2-3yrs? im not quite sure but thats my guess

I would say around 1-2 years old depending on how much and how frequently it was fed. It only looks around 2 feet long and maybe 200g. Definitely not large enough to breed yet.
