This is how a bottle of nutes goes bad. They get rocks formed in them. It's basically chalk at that point and is
insoluble and useless to the plant. So.. bottles that are separate have a longer shelf life and are not as acidic.
Dyna Gro has to be marked as hazardous for shipping.. lol cause it's so caustic.
