Rez Question

I was wondering what other people use to store large quantities of pre mixed ferts. I use organic for Veg and week 7 and 8 and for flowering 1-6 weeks Semi organic. I also use for the entire 16 weeks Canna A&B for my canna pots. So I end up with 4 containers unless I've got clones where I have 5 containers ranging from .5 gallon to 4 gallon liquid mixes. My organics especially get funky if I store them even with airstone. Any body have a suggestion?

After stinking up a couple of gallons of distilled water i've made the decision to premix only CalMg into my water and mix the nutes as I need them.
