How long is a nutrient mix good for?

I am currently using the 3 part jungle juice from AN, hygrozyme, and calmag (ro water). I want to mix this in a 1 gallon water container for my seedlings, but, it will take me at least a week or so to go through it. Is it safe to have it pre mixed that long? Or should I discard the extra as soon as I am done? Thank a ton in advance.

im no pro but i mean it should be good still just do a little stering to get it mixed back with water. and make sure that ph is where it needs to be.

Oh yea! Like blizake said, just make sure to stir it up thoroughly, and it's good for a bit... more than a week definately, I've never let teas sit more than a month personally, but I don't know the exact shelf life.

perfect, thanks for the help!
