My amateur guess is a nutrient deficiency. IFAS sites say an 8-2-12 fertilizer is best,
Here's a common deficiency that causes yellowing...magnesium.

I was at the UF plant clinic today and confirmed that the above is the most likely cause and fertilizer cure for palm yellowing. Epsom salts are less effective because that's on one nutrient and it quickly leaches. Lesco 8-2-12 plus 4 fertilizer is slow release, contains micronutrients and is also quite fine for turf. Other brands of 8-2-12 are available at big box stores.
Lesco is available at John Deere Landscape supply, Leesburg or from Fertilizer Direct, who will bring the fertilizer to your door, as cheaply as it's available retail, so I'm told. Big box stores have similar but not equal formulations of fertilizers. Palms are slow growers and slow responders to intervention. It may take up to a year to fully recover.
According to Master Gardeners, under watering of established palms is not likely the cause of yellowing where irrigation and/or rain are regular.
