I think your maybe on to something,these are sips so very little top watering.But when you water over the Gaia it beads and just runs off.Exactly what anti caking agents are made to do.With my other fertilizer like Kelp,Alfalfa etc water absorbs instantly.Do you water aggressively on top by chance? Fert companies sometimes put anti caking agents in and if we water aggressively we can get stuff to separate out like that.
Most anticaking agents are made from synthetic substances such as silicon dioxide, magnesium carbonate and iron ammonium citrate. Calcium silicate, commonly added to table salt, absorbs both oil and water. Natural anticaking agents include magnesium silicate and corn starch.
Just a total guess though
Calcium build up from hard water.I only start to care when a foriegn substance is red or blackish. Ur fine man.
Would water evaporating on the surface do this?Sips, so wicked up and evaporating at the surface? I get scaling on my taps also.I dont think thats strictly from hard water source mate. The amount required to differentiate that sized white chalky substance on the surface from throughout that sized pot would be obscene...like...not possible levels.
Still a ridiculous amount of calcite from hard water...think about how long it takes for that calcite to build up on faucets? Now look at that chunk in ur pot.. it dont add up.Would water evaporating on the surface do this?Sips, so wicked up and evaporating at the surface? I get scaling on my taps also.

Are you getting flakes like in my pic? I can’t quite see in your photo. Your appears fuzzy like mycelium??Earlier I posted this in a coco thread. I was using Blumats for the first real attempt and kept this poor plant too wet.

It's not Ca deposits.Mine definitely is flakes. My pic is fairly clear when zooming in. View attachment 5015704
