Hi Melody,
I would bet that your Catt's new growth is stunted due to lack of light. Unless you are providing supplemental light, a north window (in the Northern hemisphere, anyway) will not give Cattleyas anywhere near enough light to grow strongly or to flower.
Try moving your plant to a sunny window. But, be careful--suddenly increasing the light levels can burn plant leaves.
I think that having your orchid in basically two types of media (moss and bark, is that right?) is not optimal. (Bark and moss hold different levels of moisture and dry at different rates). I'd recommend you repot it soon, check on the roots, and then repot into fresh media of your choice.

PS Tucker, please do not stop posting. As a new-ish grower myself (I've only been obsessed with this hobby for the past 16 years or so,

) I have ALWAYS enjoyed reading your posts; they've been so helpful to me.
