Brown leaves and shrivelled bulbs on Cattleya.

[babehauss]

Hello everyone,

Could someone help me identify the problem on my Cattleya? I bought this plant a year ago down in Florida. About a month ago, I noticed the center of leaves started to turn brown and the bulbs started to shrivel up. Is it a virus/bacteria problem? Or is it a cultural problem?
The other cattleyas in my collection are doing just fine.

I live in the Northeast so I grow my orchids indoor under light during the cold months. I have the light on for 12-13 hours per day. The humidity is around 40%. I water and fertilize(weakly) most of my orchids every two weeks.
Thank,


Thanks.
