Storing mixed nutrients

[BongJovi]

I've always grown in soil till now, but after hanging about here for a while I want to try coco next.

With the nutrients that come in A+B variety ..is it ok to mix up say a week or two's worth at a time or do you need to mix it fresh every time you use it? I read that the A+B components will bond with each other in the bottle if not kept separately but is it ok to store once mixed with water?

I can knock up a weeks worth in a big water butt with an airstone in it which will see it good. Just have keep an eye on ph fluctuations
