Dabs,
Possibly posting an update w/ your concerns on the "Big Plant PPK" thread. Hopefully D9 will chime in and drop knowledge. As it seems, he has been frequenting that thread as of late. It could possibly be the SM-90 that you added to the bulk throwing things out of balance. From the 100+ pages that i have read regarding the "PPK" system, one of the many notes that i documented, one should need nothing more than Jacks Hydro + Calnit w/ ro or low ppm tap to be sucessful. Even if your inital Bulk PH was low, it should stabilize once it runs through the system and plants start to feed/Bulk mixing with your pulse. I'm hoping ya get it figured out, im in transit, once im up and runnin at my new spot. I plan on setting up (2) 4 plant (Wifi), 5 light, 10x10's per "DHF"
