I have two navel orange trees. One has great fruit, although small, while the other has thick skin and the fruit is dry. They both get the same amount of water and fertilizer. Why is this happening?

Nutrient issue. One plant may simply be taking water/fertilizer in better than the other one. This article should help: https://www.gardeningknowhow.com/edible/fruits/citrus/citrus-fruit-thick-rind.htm
