Grabbed a noid from the supermarket yesterday because of the price. It was in a bag with holes so it could be watered and air could be circulated. From what i was able to see, roots looked great and so did leaves. Took it home and noticed one leaf has a sort of "birthmark" on the underside. It's a purple bloomer and I've noticed that some of those have purple or dark red details through tout the plant. This is that color but it is just one splotch on one leaf. Thought?

Another spot on it looks like it was bruised, that one I'm not as concerned about.
