Heath, sometimes the 'buds' on the flower stem are new stems forming for more flowers, not necessarily a keiki. You might want to wait and see what's coming for a few weeks. Phals do start putting up new flower spikes at this time of year.
Btw, I have a jar of the keiki paste and it does work really well! But most of the keikis that I grew blasted or died, unfortunately. I think maybe I tried it at the wrong time of year, going into our brutal summer heat here. Maybe fall would be a better time. The paste is pretty expensive, too.
