Hi, does anyone know what is this white growth? Is it mold/pests or just buildup from hard water? Googling around didn't really help. The cutting is from begonia, if it's relevant.

    Don’t really know what the name is but it’s pretty normal, i have seen it especially strong on begonia cuttings

    From what I’ve seen on here before, that might just be more roots forming?
