Cattleyas leaves broke off at the neck of pseudobulb

[babehauss]

Hi,
Does anyone know why the leaves of my Cattleya keep on keeling over?
Is it because the plant got too much nitrogen?
Should I cut the leaves off ?

I fertilize all of my orchids with Repotme Feed Me MSU fertilizer once a week very weakly, even in the summer months. (This plant was infested by scales, but I had it under control by treating it with Acephate systematic insecticide).

My plants culture regimen for all of my orchids is as follows:
Winter months(End of Oct - May)
Light: Spider Farm grow light(10 hours from Nov and gradually 14hrs to Feb)
Water: weekly
Fertilizer: weakly weekly

Spring - now:
Outside:
Water: daily if the temperature is in the 90’s
Fertilizer: weakly weekly

Thank you in advance for your help,
