What makes orchids grow multiple small leaves at once?

[PaphLover]

I have a few orchids (sedirea japonica, a couple phals) that are growing multiple leaves at one time instead of growing one proper, full-grown leaf at a time. Why would this be happening?

The phal seems to be growing quite lopsided, though I have the non-growing side facing the light.

Is there any way to delete your own mistaken multiple post?
