Mystery white stuff on honeyberries

I received my Aurora honey berries starter plants. They look good and started to wake up, but our weather is not ready for them to be planted in the ground, so I planted them in pots . Each plant was already with the pot root ball, but in the plastic bag instead of actual pot. They are now in unheated porch, where temp is about 40F. They are actively waking up. Few days ago I noticed strange white substance on the trunks and buds. It looks like it appeared more where the bark was a little damaged and on and around buds. I remove it, it appears again. When I rub it between fingers it feels how wet lime would feel. I tried to see if there is anything alive in it, but can’t see anything under microscope. It almost feels like it is mineral deposit coming out of the juices. Any idea what it could be?

my indigo gem and treat came from Hartmann’s with white stuff on it like that. i think it was powdery mildew from being stored wet in cold storage. i planted them out in full sun and it went away.

The strange thing, they came without it! It appeared when they started to wake up. And it is too much “3-D” to be powdery mildew, I think. and it appears again after I remove it.

I don’t understand what the bottom picture is showing.

I tried to tear the white thing apart with needle. But nothing in it.

maybe hit it with a fungicide and see if that gets rid of it.

This is what I thought myself, but I can’t find anything inside. Should the bugs themself be visible?

In early spring ( and later ) mealy bugs make a ovisac
Containing very small eggs. Would be very hard to see eggs .
This ovisac looks like a cottony mass.similar to what you have.
This maybe what you have ?
Or , something else ?

The mass doesn’t feel cottony at all. It feels like mineral deposit or may be road salt residue and crashes like chalk.
