Storing nutrient mix for few days?

I want to mix a batch of nutrients and use over the course of 3 days max. Should I store the nutrient/water in a bucket with an air stone bubbling? Or would it be ok to just have in a gallon jug and shake once a day? I always heard it's not good to let nutrients sit for too long after mixing, true?

Growing in coco
Nutes: h&g cocos a&b, h&g root excelerator, h&g multi zen and humboldt nutrients equlibrium(cal-mag source)

either way is fine for a few days, just make sure to ph before using as it will change.
