What's Wrong with this Royal Palm?

Hello, I live in SW Florida and I have 6 Royal Palms lining my driveway.  We planted them all 8 years ago.  One of them has some sort of problem.  As you can see in the images, the fronds are shrinking. This has been happening over the course of 1.5 years.  New fronds are yellow and brown, and each generation gets smaller and smaller.  I can't figure out the problem.  I've made sure to fertilize it as suggested, and the other 5 palms on the same lot are perfectimage.thumb.jpeg.c1c63ceb82bc77e38d5e6a706d261a2c.jpegly fine.  Any ideas?image.thumb.jpeg.609b6353ee1a45a158841a1abed66173.jpeg

@eddiek Potentially a serious case of potassium deficiency: https://blogs.ifas.ufl.edu/monroeco/2008/09/23/pencil-pointing-palms/

Considering the palm size and cost, worth an attempt to save. Agree that it needs something. As as another pointed out, could be a potassium deficiency. It also could be age, this palm is taller and therefore older than the others. In ideal conditions royal palms can reach 98 feet high so I definitely think there's a chance to turn this situation around. Get a plant arborist to test for diseases, insect infestations, etc.

I did an at-home potassium test of the soil but it seems like potassium was pretty high.  I'm not an expert though.
