Phal. equestris keiki paste?

[Fishkeeper]

I have an equestris, about 5" across, that's starting to put up a spike. It was a keiki, just cut off the spike about two months ago, and is doing pretty well in its new home.

Would it be worth a shot to try keiki paste on the spike and see what happens? It's not a full-sized plant, but it's healthy, and the parent plant wasn't much larger. Plus, from what I've read, these guys like to make babies this way.

Would fertilizing it help the process at all? It's mounted on a deer skull, so I could spritz a highly diluted fert mix onto its roots and then maybe rinse them gently after giving it some time to soak everything up. The roots are pretty healthy, and most of them have growing tips.
