Hi friends! I’ve taken a cutting of my marble queen Pothos and am propagating it in water, which I have done many times before. However this time, there seems to be this strange white growth on the roots, underwater. It seems to be quite attached to the plant when I tried to remove it, as I assumed it was some sort of mould, but now I’m not so sure. Has anyone seen this before? Or know what it is? Thanks!
