I took a peek at its ancestry which is mostly from the Latouria and Phal sections.
Both generally want bright, filtered light, maybe a tad less than Cattleyas. I would try cutting off the fertilizer during the cooler, winter months and reduce watering during that time as well. If you can give it a month or two of cooler temperatures, it might help too.
Here's some links from the AOS on both sections:
Den. Phals
Latouria Dens
And link to Orchidroots for its ancestry:
Den. Hawaii Stripes
