How long can you reuse nutrient solutions for? i have a half gallon jug that i mixed with nutrients about a week ago, can i still use this to water my plants?
Do you know the logic behind that? I figured if the nutes in their container are good for years, why does it make it any different that theyre mixed in water?
I suppose once dissolved and diluted into water that they could more easily dissipate into the atmosphere (which is mostly nitrogen, after all) or break down somehow, but I have nothing to base that on.
