Shelf life of Nutes?(implications of using old ones)

[Frazzled]

Hi,
What is the shelf life of Nutrients(advanced nutes in particular)/ What would be the implications of using old nutes?
Thanks

Most of the chemmy stuff is fairly stable. Organics less so- watch for changes in appearance, smell. Biologicals ( ie voodoo, pihrana) can go bad fairly quickly.

The big things to watch for are fungal contamination, precipitates, weird colloidal suspensions ( free floating snot), and any change in appearance,smell, viscosity.

Implications? Weird pH behavior, lockouts, lack of general vigor- it can be hard to diagnose.

Well, I don't usually think of manure as a " hydro " nute... clogs the emitters...
