Yeah I wouldn't fret yet.

If the change in conditions was too drastic, the spike would have been
aborted. If it's still green and turgid, this is a good sign.

Seems like the plant needs a little more "input" in the form of light
and nutrients, to kick start it back into energy-sucking floral
maturation and meiosis. More light, a slight increase in fertilization
frequency and / or intensity, and you should see a good response.
