For years I've wondered wtf, more often than not when I mix a batch of nutes in the mixing barrel and set the ph if I don't use it all at once, by the next day the ph will be off. I always figured it was due to a temp difference but I recently read up about it and my bluelab meter adjusts for temp. Any Bill Nye types know whats going on here? I'm starting to wonder if up/down products aren't all created equal.
