Shelf life of mixed general hydroponics nutrients????

What is the shelf life of the general hydroponics(micro,grow,bloom) nutrients. Im not talking about the concentrate in comes in. Im talking about a gallon of it I mixed up? Its in a sealed container and all mixed up.I only have 2 plants so I am not using near as much as i mixed up. Is it ok to keep using it as long as I shake it good before each use or should i mix a fresh batch for each feeding?

it's all synthetic. You should be fine. shake well

Kept away from heat and light,mixed GH synthetic nutes serve me well up to 2wks.I never stored mixed nutes longer than that,but GH says that properly kept(nonmixed) bottles last indefinately.Just mix properly and keep away from heat and light.

I'd put an airstone in there to help with DO levels, but that's about it!
Hydro growers use this stuff and only change their rez ever week or 2 so it's definitely stable

a buddy of mine keeps his in teh fridge but im not so sure bout that becuz if it gets too cold i think it might cause precipitates to form but dont quote me on that cuz im not sure that would b a prob

anyway like they sed if u keep them away from heat & light ur fine

ive had jugs of Advance Nutrients mixed up and sitting for a couple months once and they were perfectly fine when i used them
companies always say less than is really ok becuz they gotta CYA yanno
like canned food they put expriation dates on it but if u store it rite it lasts for decades or more
