Hello Josh when I first read you're post I mistaken it for 28cm and thought there's no rush, I'd get more vegitive growth on it. However at 28 inches I would say induce flowering and see what happens
Like Sativagrowin says it's going to get big.

I would like to see more growth, more leaves and it to "bush" out more but at that height I would have to flower
