What is wrong with my cattleya? (Picture)

[Kateryna]

Hi,
Could you please identify what's wrong with this cattleya and recommend how to treat?
Also, its flower spikes turned black before the buds were able to bloom or even fully develop and I cut them off. On the pictures the spikes just started turning brown.
Many thanks in advance from me and from the cattleya.

Did you take it out of the pot, or is it a new plant? What are your growing conditions?

The plant I see looks fine. Many Catts. develop spots when scratched or bumped.

Yes, I took it out last weekend. We have it for about 4 years now.

It didn't bloom 2 years in a row. The flower spikes grow and then turn brown and then black.

It grows outdoors in the South Florida environment, a mix of orchid bark and orchid moss, watering 2x week from a hose (fine mist, drinking tap water), hanging in a ceramic pot with holes for orchids, in the shade but it's gets brightfor some hours.

What are you feeding it? How much? How often?

Miraclegro pallets are in the pots.
Cal-Mag once a month (or once in 6 weeks).
Attaching pictures
Thank you very much

Looking at this plus your outdoor Phals. losing flowers on spikes, I wonder whether all this may be due to thrips insects in your garden. They are a known problem in Florida. The Phals. have that appearance, and your description of what is happening to your Catts. also sounds similar.
