I'm going to make a batch of dry ferts tonight, I mix them with distilled water. Once I mix them can I put them in the fridge? Or do some have to be stored at room temperature? What's the shelf life for ferts once they are mixed with water? I know you should only make enough iron for a couple weeks but what about the others?

They don't need to be refrigerated. Some people do this to prevent mold from growing in the micro mix. Adding a teaspoon or two of vinegar or some excel will prevent this. The shelf life would be years.
