Cattleya Pradit Spot question

[Tecin]

Hi. I have a cattleya pradit spot for seven years now. Two years ago I found out that this cattleya is one of those that need some kind of "winter rest" so these past two winters I've moved my orchid to a cooler room and watered it less frequently. Since I started doing that, the orchid has tried to grow two flower spikes, one last Spring and the other a few weeks ago, but nothing has come out of it. I don't know what I'm doing wrong. The orchid is in front of an east-facing window. Receives direct sunlight for at least three hours. I fertilise it and even feed it calcium. But nothing. Does anybody has any suggestions? Thank you.

When you say it “grows flower spikes”, do you mean complete spikes or just sheaths?

Has the plant ever bloomed before, or is it maturing to the point of doing so?

What is your feeding regimen? Formula, measured amount per volume mixed, and feeding frequency, please. Do you continue feeding during the “winter rest” period?
