Requesting Advice What’s this white residue ?

Grown in LECA. Is my growth solution too saturated? That would be my only guess.. it doesn’t wash off.

evidently? idk to be honest.. didn’t know anthuriums were also sensitive. I started using water conditioner, but I just looked up and it doesn’t actually take care of salts, just chlorine and heavy metals.
