There is a layer of white substance sticking onto the green root tip of my baby Vanda's new root. I water it with overnight tap water mixed with a tiny bit of fertilizer, diluted according to the fertilizer's package instructions. Initially I thought that the white substance might be the result of too much minerals, so I switched to using distilled water (with no fertilizer added) for one day but the white substance was still there.
I have no idea what this is but I'm afraid that it will eventually kill the green root tip! Ever since I bought the vanda, I have been hanging it in mid-air because the humidity at home is high already.
Does anyone know what the white substance is? Any advice/suggestions are welcome!!
