I would have your soil tested. Yellowing of the leaves is typically either an iron or nitrogen deficiency. When was the last time you fertilized the tree? It may need nutrients. If you have not been fertilizing, start doing so and, regardless, have the soil tested to see if you have any nutrient deficiencies that need to be corrected. Here is more information on fertilizing citrus trees: https://www.gardeningknowhow.com/edible/fruits/citrus/fertilizing-citrus-trees-best-practices-for-citrus-fertilizing.htm

In addition, it could be a watering issue, possibly not enough. Citrus plants require lots of water. This article should help: https://www.gardeningknowhow.com/edible/fruits/citrus/tip-on-water-requirements-for-citrus-trees.htm
