Expiry dates for Component Strong, Component ABCK and 1+2+3+ powders

[DrFlu]

Hi Everyone,
In need of some help and advice. I've been mixing component 1+2+3+ and dosing for a few years now, but ive just been caught out with no more powders and ABCK.
I have visited all the shops near and far my area, and they have no stock or only now carry expired stock. (Australia, NSW)
Does anyone know if it is ok to use expired powders and ABCK? is the expiry date only just for requirements? I see the Component ABC 2L bottles don't have any expiry date listed on it for some reason, but the 4 x 75mL pack has one.

Calcium (expired 08/2023)
Magnesium (expired 08/2023),
KH buffer (expired 07/2023),
Reef Mineral salt (Not yet expired)
Component ABCK (expired 08/2023)

Any help would be really appreciated!
