@Modawg2k If I remember right, you're in Phoenix as well. It's heating up...
...so I would guess that's what is causing the frequency to pull in, but I'm with you that yours seems over the top. I'm attaching my setup for comparison. It looks like you lowered your root depth ? I'm not sure if that affects the frequency or not.
Did you alter your crop coefficient to 0.73 ? Mine is at 0.65, which is the default for Warm Season Grass. I think @franz might have commented to that the manual changes of CC aren't being taken into account yet, but I could be wrong.
Also compare your moisture graphs (w/details on) to mine.
