Hard leaves on Cattleya

[Seachelle]

Hello! I have a Blc. Eagle Island 'Sangia' that I bought about a year ago. When I purchased it, the leaves were normal in texture. Now, they have gotten really hard and curled. The color has also sort of bleached out of them, and they look yellowish. I grow under lights and am thinking maybe it's getting too much light. I have since moved it to a different spot. The roots look great and there is a new shoot coming. Could it be something else? Thanks for the help!
