I agree with Bob, it's probably past due for a good repot. Once you repot it you will likely see the plant start into a vegetative growth cycle. That's good. It's making energy for next year's bloom cycle. I typically see spikes beginning to emerge in October/November, and they usually start blooming now. As everyone else has said lower temps in the fall are usually what triggers spike initiation. Keep in mind your plant has be be healthy before it will bloom again. Once your culture improves the plant will reward you with blooms again.
I also meant to say I wouldn't leave the Keiki on there indefinitely. I will suck the life out of your mother plant. As soon as it has enough roots to sustain itself remove it and pot it up.
