Angraecum-sesquipedale New Side Growth

[allars]

I acquired my first 2 Angraecum-sesquipedales about 2 years ago as a young plant in a 2.5" pot. They seemed to be growing well with Vanda conditions. About 2-3 months ago, the one in the picture stopped growing from the center and put out 2 side shoots. I have seen this in my other orchids, but not at such a young age. Any advice or suggestions are appreciated.
