Do nutrients go bad?

I have some Botanicare Nutrients from 4-5 years ago. Grow, Liquid Karma, Cal-Mag, and Bloom. The bloom still has the factory seal. Are these still good? When I open them and give em a sniff, they seem to smell exactly as they did when I bought them. I have used a little bit of the grow over the years for struggling houseplants and it always helped and never hurt anything.

I would say no as long as its been sitting indoors..i would pour everything out in a dried out jugg to see if there are any sediments. If not i would use them regdaless of age

I know my Dyna-Gro will start to precipitate out after about a year. I'm guessing other nutrients with high levels of dissolved solids will as well.

temperatures that go extreme cold to hot and hot to cold can zap and kill things down. how was the temperature kept over those long years?
