yellow spot on leaf - new orchid HELP

[omlitt2]

I just purchased this phalaenopsis (currently in bloom) from trader joes and noticed this spot on one of the leaves (see pictures) a week after getting it home by a southwest facing window. It seems to be getting a little bigger but not much. Any advice? Should I be worried?

Other details, the soil was very wet when I received and I let it dry out very well before watering again. I thought it was odd that it was that well-watered, I've read that it shouldn't be this wet. Any tips on assessing watering frequency? I have been taking the inner pot out and water from the tap and let it drain completely before placing back in the decorative pot after watering.
