Epi. Illense Hybrid.... unhappy

[bellina9]

Hello,

I've had an epi illenese hybrid for about 6 months. its not grown at all since I've had it and now has dark brown edges on some of the leaves. I repotted it and found some root rot. but there are still some nice looking roots.Today I notied the top left is not almost dead. I spray it with water about every other morning. and it gets alot of sun. what am I doing wrong??? For some reason I feel like this shouldn't be that hard to grow!

Thank you for any ideas!
