with Hetty, you have some plants that will have roots.
Your cuttings are at least two weeks ahead of what mine are doing. Even though all my cuttings are firm, the majority of them have been in the buckets of perlite since last fall. I am thinking about re-cutting those ends and starting the rooting process anew. Maybe these cuttings need a "reminder" of what they are supposed to do.
There comes a time when patience has its limits.
