## Questions & Answers

**Q: Is this organic?**
A: This product is not organic. General Hydroponics has a sister brand General Organics which has CAMG+ which is here: http://www.amazon.com/General-Hydroponics-Organics-CaMg-Gal/dp/B007RQSPG6/ref=sr_1_3?ie=UTF8&qid=1432227928&sr=8-3&keywords=general+organics+camg%2BAs mentioned, organics is different. 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
