Cattleya bulbs getting wrinkled, new growths skinny

[pokefan_nat]

Hi I’m new to growing cattleya orchids and I don’t think mine grows sheaths and idk if it’s going to bloom. I need some help because it’s also a hybrid. I purchased it in April so maybe it’s just not ready to bloom yet. The vendor said it was from Hawaii and is mature. The bad thing is I don’t get good sunlight at home so I’m using bright red and blue LED lights (it said they were full spectrum but I’m having second thoughts because the vendor isn't on amazon anymore and now i'm learning that full spectrum is white light) I water it every 7 days and fertilize every 2 weeks. Sometimes I spray the leaves but I'm not sure if that's helping humidity. If there's anyone from Louisiana that grows cattleyas? In what conditions do you grow your plants? (Im thinking about getting an indoor plastic greenhouse to increase humidity)
