Your grapefruit tree may have a little fungus, but I believe the main problem with the tree is that it is greatly under fertilized. A tree that size should be fertilized 3 times a year. Many growers in your area use either a 6-6-6 or a 8-8-8 formula fertilizer, or some formulation close to those ratios.
