Cattleya (Hsin Buu Lady) won't bloom

[Possum-Pie]

Being February, all of my Phals are budding/blooming. I bought a Cattleya Buu Lady at a show last Feb. and it was full of striking blooms. I waited eagerly for this Feb. to see it bloom again, but nothing. It has hardly grown at all in the year I owned it, and has no trace of a spike. I water/fertilize "weakly/weekly" and it gets full morning sun year round temp 65-70F. It is healthy looking, just not blooming.
