Do DIY Ferts Go Bad?

If made at home using distilled water and dry fertilizers to make a solution, what kind of shelf life does it have? Should glut be added? Or should the solutions be refrigerated?

That's an interesting question

I add 10ml of glut just in case otherwise it just sits in the cupboard out of the light. I've never noticed it looking off or smelling different.

There is bacteria that grows in the micro mix. I tend to just mix a liter at a time and freeze half of it.
