I ordered PMDD ingredients from a hydroponics website based in Canada
about a year ago. The iron + trace mixture has been starting to smell
really bad lately. Smells a little like a dead fish. Anyone know if
this stuff spoils? Can I still use it or do I need to order a fresh
batch?

The dry powder smells?

I've never heard of the dry powder going bad, but if it smells like a dead
fish, I'd think twice about putting it in my tank.
