My Sunshine Ligustrum Were A Vivid Yellow But Are Now Turning Darker Green With Shriveled, Brown Bunch-type Blobs On The End.
In NW Florida. Any ideas? I have 6 planted in same conditions. So far only two have the problem. Have tried spraying with Fertilome Triple Action - no results. When they get water, it is thru rain or sprinklers. Surrounded by landscape gravel instead of mulch.

It is likely that they are stressed or infected from being overwatered. They are quite drought tolerant and prefer not to be left saturated for too long.
Usually rain will be more than enough water for them, especially in your area.
I think that the best course of action from here will be a fungicide. Spraying the upper portions will help reduce infection. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
Make sure to cut off the infected ends and dispose of them well away from the area. This will prevent further infection.
