So everything has a shelf life... However the NPK will always be available in the nutes. They are elements, and will not degrade on their own. Not to say the rest of the goodies in that bottle wont "spoil" but you should be safe. One year is not all that long.Wow! I am excited to have a bunch of new friends. I do have a question. As I am a 2nd time auto grower, I would like to know how long organic bottled nutes last? I am using General Organics that I have had over a year. Are they still good or need to be replaced?
