Depending on how regularly, watering could be the cause. Once established, they will only need water during times of severe drought. The leaves will curl inward long before any drought damage is done, as this action will conserve water.
Unless it is showing these symptoms, then it will not be necessary to provide extra water.
Saturated soils, and citrus need for sulfur will make for the perfect environment to invite sulfur reducing bacteria. These will acidify the soil, and cause the smell that you are experiencing.
There won't be much need for action. If you would like, you can add just a little DOLOMITIC LIME sprinkled to the area to raise the pH slightly. Otherwise, just let the area dry out thoroughly between waterings, at least down to 4 or 5 inches before it gets any water at all, when possible.
