Spider mites on palm?

[Golden10]

 Hello,

I have recently noticed these small red spots on my juvenile Adondia Merrillii and  Ravnenea Rivularis. I didsome google searching it looks similar to a pest of some sort. These palms are planted close to each other so I would imagine it’s the e same pest

 

thanks

Spider mites aren’t as common of an outdoor pest as an indoor pest. Also, they are evident on the undersides of the leaves, commonly identified by the webbing they produce and their tiny red bodies, which are way smaller than the dots in the picture and are honestly too small to get on camera.
That being said, the damage cause is unclear. Do you see any visible bugs?

Looks like too much sun to me.

No obvious bugs. These have seen full laun all summer but seem to have gotten worse recently.. I have fertilized them a few times and one last time in early fall, not sure if that’s the culprit
