Problems with phalaenopsis orchid - Yellow leaves

[minerva]

Hi All!
I got a new phalaenopsis last week and it was in good condition when I purchased it. Today I noticed one of the leaves is yellow and the edges are brown and shriveled. The roots seem to be in good condition, it is in indirect sunlight, and a clear plastic pot.

I removed it from the ceramic pot I purchased it in- and it was not sitting in any water. It is potted with bark and is not overly wet. I just watered it yesterday.

I attached a pic of my yellow leaves. Is my orchid dying?

Does anyone know what might be wrong? Thanks for the support!!
