2nd Year Crab Question

[ERClover]

Got this beauty as a bare root from Arbor Day Foundation last year, one of two out of twelve to wake up. And wake up it did, it grew a ton last year. This is my first time overwintering it and it appears to have made it through fine, however I am noticing a lot of what I would describe as white hairs on the branch tips and buds. Am I dealing with a fungal issue? I’ve hit it with some Neem oil a week or so ago and then just started a cycle of preemptive Infuse as a rust deterrent (my ERC has already shown signs which I am treating unfortunately). I think the crab is just a little hairy as it hasn’t really gone away but want to be sure. Couple history photos and then the white substance pictured.

We don't have cedar rust down here so I can't be sure that's not what your tree is showing but most of my crabs have hairy buds so I would just observe for now.
Bonsai is much more fun if you don't go looking for problems where there are none.

All of my crabs have furry buds and young stems. In Japan crabapples are often referred to as furi-kaedo

looks fine to me - wait until it buds out and you will see rust if it has it

Appreciate everyone’s input. Probably just a little paranoid.
