Just be sure to have good biology going on in your roots. Try organic compost teas such as Organics Alive or Earth Juice's Bio-Righteous to really boost biology and help nutrient breakdown. **Q: Does this lower ph?** A: It should lower ur ph . 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by E***X on February 10, 2026* 非常にいい商品 ### ⭐⭐⭐⭐⭐ Review *by B***N on June 10, 2024* 自作水耕栽培器でトマトを毎年育てています。 尻腐れが発生するので購入してみました。 結果、尻腐れは、無くはないですが、実付きの割には非常に少なくなりました、効果あると思います。 ### ⭐⭐⭐⭐⭐ Review *by A***R on July 16, 2020* Showed up in perfect condition, looks like a new fresh bottle, not one that sat on a shelf for 3 years.
