Is there expiry on Nutes

[Sativajoe]

Hey all, haven't had a grow for a bit, but planning one.
Found sum Nutes in the cupboard A+B (grow + flower)
Must have been there , well sealed in shade for 3 years
Can't seem to find an expiry date on em
I'm assuming they still be good for some time, ideas please

If there’s no expiration date, and nothing has precipitated out of solution onto the bottom you’re likely just fine.
