Help please! Leaves turning brownish..! :(

[julianitica]

Hello everyone! my name is juliana,, and i'm new to this, so i would appreciate if you can give some advice!

I've had my orchid (which i will post pics) since almost a year ago, and it has been fine,,,Almost 2 weeks ago started blooming again, which i was really exited but i just noticed today the leaves are turning browinsh and wrinkly.
i water it almost once a week always making sure the soil is dry,, and it seats next to a windows were it receives filtered sunlight for some hours.

i think the pot could be to small for it,, could this be it?
should i report?

Thanks for any advice you can give me!
