It looks like the birds topped it off above the second node.
That is a good thing as it appears it will have 4 main stalks.

Did you recently re-pot it to a larger pot ?
If so, the roots are spreading instead of above ground growth. (Normal)
As soon as they root out they will explode upwards.
As long as you keep them healthy.
I would move the light up a tad and see if it stretches a bit more though.
