It's probably too much water, if you have had rains like we have lately. Mine spot up the same way because of too much water. They still bloom fine, though. I wouldn't pull the leaves off, unless you think it's something else, something that spreads. Without a pic, though, I would chalk it up to too much water.

Thanks funnthsun, we have had a lot of rain. I'll stop being OCD about the leaves and just let it be. :)
