    Default Do nutrients go bad?

    Hi,

    I have 80L of nutrient mix left over from last res change which as been sitting there for about 3-4 days. Its RO water mixed with Plant Magic Hydro chems. Is it ok to use for res top ups or should I start fresh? At what point, if at all, does it "go off"?

    Cheers

    I've used 6 day old solutions before, it was the Canna range & I never noticed any problems, but if it doesn't smell or look like shit, I'd use it, you'll soon find out if it's no good😬😬

    On the other hand, I've been using nutrients that I open 5 years ago on my current grow, also no dramas.

    As long as it’s kept cool, shaded and has water movement I think it’d last a very long time.
