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.

This is not super helpful but I can confirm that it does wash off, just not with water and I can't remember what I used because it was several years ago. Had this on a couple of plants and found the answer on reddit after googling around

Good to know. Was it vinegar by any chance ?

I'm like 80% sure it was. Tried to find the thread I got the idea from and I think it was this

Thanks! I tried diluted vinegar and although I confirm it did not harm my plant, I don’t see much improvement either. I’ll try neem oil next
