Black Spots on Cattleya

I've found some black spots on the leaves of my cattleya.
What should I do?
Please give me some advice.
Thank you!

Maybe sun burn & lack of water.

That looks like the start of fungus. You can treat it with a fungicide or cut it and treat with peroxide and cinnamon. Increase your air circulation. Be sure to sterilize your equiptment.

That looks like it could be mite damage, and has caused a secondary infection. I would cut it, and treat accordingly.

It looks to be a bit fo bacterial or fungal spotting. I'd apply a fungicide, increase air flow, and monitor to see that they're not spreading quickly. If they do spread quickly I'd cut the spots off.
