PPS-Pro recipe storage

Hello I am just getting started with dry ferts (thanks to Orlando from GLA) and now going to use the PPS Pro Solution. I will be using a 500ml bottles to mix in (macros and micros). The question I have is how long is the mix good for once I combine each of them in the bottles? Do you need to refrigerate or anything special with it once it is mixed?

For macros, I mix it up in large batches and just let it sit.

For traces, I mix it up 500 mL at a time. Lasts 6 weeks or so. I don't refrigerate it. By the 3 week mark I start seeing a little fungus, but I never have any problems.
