I've had Cutting Edge Solutions for more than a year and a half. It's been stored in my closet in a dark cool temp place. Anyone?

I try and use nutrients within 1 year. bump, I'm not exactly sure how harmful it is.

Well, if it's sealed up, it's probably okay. But if it were me, I would get a new bottle.
