My main question is still if Fluorite can be considered to supply nutrients (let's say micros and trace elements) without first being "enriched" by being used in a fertilized water column. It doesn't have much to do CEC.
Flourite is an inert substrate, which will not supply any of the needed nutrients. The first thing that has to happen before a "rock" can supply nutrients is for some part of the rock to dissolve in the water. That makes the elements in the rock become ions, and plants can only use ions. But, Flourite does not do that.
