Are these roots?? Fiddle leaf fig water propagation

gootza

Hi all, this is my first time water propagating a FLF. Just wondering if anybody could tell me if these little white lumps are roots forming or if it's some type of mould or something? The cutting has been in water for about 3.5 weeks.

I think the best thing to do is to wait and see. 😊
