Keiki on dying Denphal

[Blooferlady86]

Hello all!

I have (had?) a denphal that came down with a bad case of a brown spots, couldn't recover, and is basically on life support. The canes lost their leaves and two of the three started to rot, so I took a chance and bought some keiki liquid. Lo and behold it did indeed create what looks like a keiki near the top of the healthiest cane. This was back in April 2022. I've included some pictures, but since this is my first keiki and the whole thing was a bit of a Hail Mary play to start with, I'm looking for advice on getting those roots to grow. It looks like a healthy keiki, and it's got 2 very small (about 2cm) roots and a third growth that I *thought* was a root, but now looks like it might be another shoot or cane?

I've been watering the mother plant as often as I can without rotting the remaining roots, such as they are. The plant is on a humidity tray to boost humidity as much as possible.

Any help with my little science project here would be appreciated!
