Brassia Orchids not doing well, stopped blooming

[denvervet]

I hope I am in the correct forum, I looked up Brassia on line and it said that it was in the genus of Oncidiums. I have had this orchid about 3 years. I bought it from an orchid Judge here in Denver. It bloomed the first year then stopped. As you can see the leaves are crinkled but they've been that way since I got it. I split this orchid about 2 months ago, it was one of those "do it or die" moments.
This is a Brs. longissima X ochraleura, forgot to mention that! Sorry.
Anyhow, it is in large bark, It gets watered 2 X a week because of very low humidity in Denver its dried out when I water it, I use Miracle Grow Plant Food 2 X a month full strength, I mist it when I water it and its in bright light under a skylight where Plals flourish.
What is wrong with this orchid and why is it not blooming? Should the leaves be crinkled? Any suggestions are appreciated. Thank you.
