Hi guys, I've recently been given all of these nutes by a friend who is moving and doesn't need them anymore. He tells me they have been in storage between 3 and 4 years. Does any of this stuff expire? I havent found any dates on any of the bottles. I'd hate for something to go bad and kill or harm any plants.

The salts h202 Ph up and down are probably fine but Npk will decay. They may work but who knows the ratio now.
