Storing organic nutrient mixes?

Hello every one.

I'm wondering if it is possible to mix and store large batches of organic nutrient solution that will later be used in soil.

Would it be ok to mix a large amount of fertilizer and leave it in a tub with an air stone for a month or longer?

I'm using General Organics if that makes a difference.

You might get some bad bacteria if you store for more than a day. You will know when you smell it.

will it work better if you store it in the fridge?

I've mixed & stored for a little over a week with no probs (yet).
I don't mix much at a time though. Seems I'm alway changing the blend according to what I'm seeing the plant(s) do.

I store under the lights with the plants. Well, not actually under the lights, but in the room / cab. Not wanting to mix veg with flower plants (and other way) is one reason. Another is applying at room temps.
