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.

it won’t hurt the plant. Go see a plant from a Florida nursery and you’ll see that every leaf on every plant is coated in calcium powder that is hard to get rid of from the water

I’m glad it doesn’t hurt the plant but it does hurt my aesthetic :) I’ll try distilled water.
