Chiloschista exuperei: To fertilize or not to fertilize?

[KristenReuel]

I have been told that chiloschistas go through a winter rest, so I stopped watering mine as frequently starting Oct 31 and I stopped fertilizing it altogether.

Over the past couple of days I've noticed at least one spike forming. 99% sure it's a spike. There's another growth that I believe could also be a spike.

My question is, should I begin fertilizing the plant again? Does it need to be fertilized to support the growth of the spike(s)? I live in currently dreary Ontario, where the days are not getting any brighter.

I'd really like this orchid to bloom, as it has sentimental value to me.
