Phaelenopsis 1.5 years, no luck with new stem. New leaves, new roots, what do?

[gliss]

I've had this baby for almost 1.5 years. The only flowers it had was when I got gifted it and it was gorgeous! I cut it to the inch node when the flowers fell off, re-pot, and have been watering every two weeks and giving it food monthly. Since then, new leaves and new roots have popped up but no sign of a new stem. The brown stem is the old one that I cut back then. Not quite sure what else to do

Climate is usually moist warm, 12-25C indoors through year. Indirect sunlight on kitchen sill ~3m from closest window. Unless there's something that I'm completely missing, I'm considering re-potting this baby Any advice appreciated!!
