Catasetum troubles

[The Orchid Boy]

I've become a little concerned about my Ctsm. Frilly Doris. It has little yellow spots on the leaves and has sticky dew on the undersides. I really sure that it isn't an insect pest. I've looked all over for pests and even went out with a flashlight to check it in the night. It is under T5s and fairly close to them. Could it be just a little too cool for it currently? 75F to 65 F. It's been a little cooler in my growing area than usual. I could grow it outside. It also has a teeny tiny thing that would develop into a growth. I think it would if it was warmer. That's my best guess, what do you think?
