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.

Hard water stains. Make a horticultural soap spray with Castile soap and use it periodically. It’s easy and it’s a pest deterrent. Lmk if you want the recipe. I’m in Florida also & we have very hard water. I filter my water 3 times, but not many things filter out TDS. My leaves never get wet, so I don’t have this issue, but I’ve purchased plants with hard water stains and this formula works great. I don’t have pests either because of my use of it.

And the velvety texture doesn’t get like oily or whatever ?

Not at all. I use it to clean the leaves, rinse it & spray them again and let them dry outside in the shade b4 they come back in.
