Bent leaf on Psychopsis

[cbennett4041]

So I lost a Psychopsis mariposa a few weeks ago. The flower store (not orchid store) I bought it from kept it way to wet and overpotted; I thought it was worth a try at $10. You win some, you loose some.

Hoping not to loose twice, I thought I'd ask about my other Psychopsis. I purchased it at the same time from the same place, but it's doing better than its late sister. My question regards its newest leaf, however. It seems as though it's seen an unfortunate crease, but I don't remember it happening. I just noticed the leaf flopped over about a month or two ago. Since then, I've tied it up for support.

If it's not from mechanical damage, perhaps it lost turgidity due to underwatering? I was letting it dry fairly long since it was so wet at the flower shop. Let me know what you think.
