Hello, I had a question about storing nutrients in water for up to a months time. For example I have put 2 tsb of blackstrap molasses in a closed gallon container of water. I also keep Fox Farms nutrients like big bloom and tiger bloom in a gallon of water premixed and I put the cap on them and leave them until I use it up and then create another batch. Is it safe to leave nutrients premixed and pH corrected in water jugs for no longer than 1 months time till they are used up. Should I keep the cap on them or off, is blackstrap molasses safe or does it spoil?
