Well I'm thinking that when I premix my current nutrients from advanced nutrients it may keep for a week, but have to shake it vigorously before use. Also, not sure how some components then change.define stable? Fertilizer minerals don't "go bad" since they are stable minerals.
So, if I mix MC, dose it for watering, will it keep 1/2/3 weeks? Will it settle, do I need to shake it before use or even install a bubbler?
Thanks
