I have ab Old Man Palm that was planted about 2 years ago and was about two feet tall. The first year it grew big leaves and gained in height to about four feet tall. This past winter in Florida we had a cold spell with about five days bellow 40f. degrees. Since then the leaves that have come in have a few yellow spots close to the folds and the leaves keep coming. The problem is the crown is getting so crowded because the Palm is just not gaining in height and they are forming a cone a the top and starting to disfigure because they can’t open all the way or are growing into other leaves. What’s going on with this Palm? 

@PalmGuyPSL a couple of photos would help!  Usually a couple of nights in the 30s won't damage an Old Man Palm, but some Coccothrinax are pretty sensitive.  I have a couple of Coccothrinax here in the NW Orlando area.  Both Argentea and Barbadensis survived frost and 27F, but both of them got a crown infection that was causing stunted and brown/yellow spotted leaves.  I gave them a squirt of Daconil mixed with Hydrogen Peroxide into the crown, and by April they were growing normal leaves. 

Another possibility is a root fungus or a boron deficiency.  If there's a root rot problem (too wet or too mucky soil) then the new leaves might grow out smaller than normal.  A boron deficiency can cause "accordion leaf" or stunted leaves.  See the below info sheet on boron:

Here are some photos of what is going on with the crown and how crowded it is because it’s not gaining any height.  Leaves are normal size up until the last four which are all crowded together.

Looks like cold damage. I wouldn't worry since its pushing new leaves.

If you are getting miniature leaves, this can be a sigh of manganese deficiency, often with some leaf necrosis too.  Not sure what your soil is like there, but in the sandy, alkaline soil here, it’s pretty common.   I’ve had it on a couple of different palms.  Usually respond to a couple of generous hits of Mn.   

The leaves are the right size.   The problem is they are overcrowding the crown and the palm is not gaining any height.
