roots organic shelf life

From my last grow 3 years ago I still have almost full bottle of nutrients. They have been in a box in my closet do you think there still good to use in my next grow i'm about to start?
I've got
hygrozyme
budda grow
budda bloom
trinity
amino aide
hpk
hp
extreme serene
ancient amber
big swell
Should I throw them out?

Unless its got a use by date ...it should be good, but many sharp operators want you to use their stuff,
one way is to have a use by date ..dude its bottled sewage you and your plants are fine

That's what i was thinking. Thanks.
