Watering Schedule for Grapefruit Tree

Question

I have 2 citrus trees, grapefruit and orange. They have been in the ground for five years. For the last 4 years, I have watered them every 5 days for 3 hours. I have them on a drip system, 4 emitters at 2 gal/hr. That equates to 24 gals every 5 days. That schedule worked great until this summer. Now after that 4th day, the leaves start to wilt. So changed the cycle to twice a week for a total of 48 gal. Now the leaves are turning yellow and I am going crazy. Trees height are 6 ft with a drip line diameter of 6 ft. Soil is a mixture of some clay, sandy loam and mulch. Will appreciate any valid info that you can provide.
