Dolomite

[Phoenikakias]

Is there any merit in adding some dolomite (Dolokorn 90) in to the soil mix of Coccothrinax (argentea or argentata) and Leucothrinax morrisii?

not for cocothrinax:  https://www.gardenia.net/plant/coccothrinax-argentata

but leucothrinax wantsan alkaline pH so yes it is probably a  good idea if your soil is neutral or acid.     https://davesgarden.com/guides/pf/go/64291/#b

You really need to know your soil pH first.

My soil mix consists of perlite (neutral), zeolite (slightly alkaline), coir (acidic) and peat (acidic). I am talking of course abut soil mixes for pots.
