Laelia purpurata sunburns?

[Nico]

I've got this Laelia purpurata for 3 days and I think I've allready made a mistake.

I've just notice some brown spots on 3 leaves from 5. On Sunday I let some plants in partial sun, on my balcony, and watch them closely (I usually keep my catts inside). This is the only one with these simptoms.

Are they sunburns?

Can I treat them somehow?

Am I going to loose the leaves?

Sorry, but is my first experience of this kind with a laelia. I can't tell you how worried I am and how guilty I feel....
