laelia anceps spikes keep aborting

[beaniebeagle]

I have had it for about 3 years, grows well. Each fall the flower spikes fail to set bud and just stop growing.

It gets plenty of light with some midday shade in summer. It has been sitting in a southern facing window for the past month with the spikes not growing anymore. Just like previous autumns.

Any suggestions? or just give up on it?

I had only one flower on it since I bought it, and that happened in the spring. Definitely looked like anceps
