While we're on the subject of Keiki...should I pot now?

[Corsetière]

Hello!
The backstory on this is that the mother plant was a Lowe's purchase with extensive root rot. After I got it home, it sprouted the keikis. I cleaned up the root rot which left pretty much no roots on the mother plant. It had a brief renaissance after I cleaned up the dead roots and that's when the keiki grew all the roots it has now. However, the mother plant' leaves continue to look wrinkled and limp and now the keikis are losing the turgid quality to their leaves too. I looked at the spike recently and noticed it looks like half of the spike is dying on the side of the oldest keiki. This really concerns me. I know people say you should have 3-4 inches before planting the keikis, but I am not sure what is going on and wonder if it it best to try to separate them from the mother now before they die? I just measured the oldest keiki and it looks like it has about 3 inches of roots and the youngest has about 2 inches. Any thoughts or experience on this?
