Trying to propagate from a tree cutting for the first time. Is this white stuff mould or roots forming?

Thank you!

    Biofilm, it’s like a precursor to rot. Switch out the water and rinse off the prop, spray it with alcohol before refilling the water and placing it back in.

    Yes.
    The water should be changed regularly until they stop doing that maybe cut the last inch off and start over
