Is this snail damage on my Intergeneric Oncidium?

Aloha!
I'm relatively new to the orchid world and have much to learn. About a month ago I purchased an Odtna. Pacific Paranoia 'Other Side of Cool' and it has been growing quite well and has set off two new spikes from the new pseudobulbs. One of the newer leaves is showing signs of some kind of damage. It almost looks like something chewed the outer edge of the leaf. It's only on one leaf though, so I'm not sure of its snail damage or some kind of fungus eating away at the leaf..? Any information would be very much appreciated.
Mahalo,
