My tap is 7.8 after adding all my stuff my ph is 6.4 . ... run cal mag lil higher then bottle shows I run mine at 3ml gal thing bottle says 1-2ml and I also run it all way threw , I'm using tap water at 89 to 114 ppm .. hope that helps .. **Q: Do i add this before armor si to Ro water? Or the other way around?** A: You absolutely add the Si first, and its recommended to wait 1hr. after adding the Si before checking the T.D.S.(total dissolved solids), and checking the P.h. I will add my Si to a bunch of my gal. jugs of water close the cap and set them aside till the next day then add my cal-mag and the rest of my nutrients. Its just the way I do it, but you should wait the hour before checking if you want a very accurate reading. **Q: Does this contain silica.** A: No it dont i use gh armor si with it its the best and highest concentrate of silica and very reasonably priced ## Frequently Bought Together - General Hydroponics CALiMAGic 1-0-0, Concentrated Blend of Calcium & Magnesium, Secondary Nutrient Deficiencies Helps Prevent Blossom End Rot & Tip Burn, Clean, Soluble, 1-Quart - General Hydroponics pH Control Kit For A Balanced Nutrient Solution - General Hydroponics Flora Series: FloraMicro, FloraBloom, FloraGro - 3-Part Hydroponic Nutrient System, 1 qt.
