Yo Im a recent graduated hort major, and my best advice would be to keep your pH around 5.8 to 6.2. Your plants can't take up most of there micro nutrients at a pH level below 5.4 or so. A lower pH is only better toward your finishing stages. The reason your pH keeps rising is b/c you are using good stable nutrients and they are designed to stay around 6.0, if you really want to drop your pH that low i would cut out the fulvic acid and that should help.
