Newborn paph care instructions

[PaphLover]

This teeny growth came away from the larger plant when I was checking if mama needed to be repotted. It seems to be doing well on its own in its little bed of moss. It's even growing a new leaf! Been on its lonesome since August.

Any tips for ensuring its growth? Can I fertilize it as I do the other plants? Does it need a weaker solution? What about the spray-on fertilizers?

Thanks!
