how long do nutrients last

How often should nutes be replaced

I replace mine when they run out.

Lol i mean i is there an exspiry date? My nutes have been stored for 12 to 18 months. Can this be bad for my plants

I have nutrients that have been sitting for 12 to 24 months are they safe to use on my plants

Long long time. Just store them properly.
