It's the same circle jerk, chem ferts & lab supplements. Clorine, a chem, is added to our water. Our bodies is not chem based & therefore cannot breakdown the injested clorine in our bodies. It slowly builds up, like root lock. Caltrate is lab made, it is a poor quality of calcium and does not absorb well, causing weak bone structure. NPK is just 3 of many trace minerials & nutes needed by plant life. MG does appear to work wonerful, & shooting Meth certainly feels wonderful, but both breaks down the immunity system, making us suscepitable to dieseaes, inviting insects & parasites,etc. One tablespoon of healthy living soil has literally Trillions of teeming microbial life, all working to balance the PH, airate, 'airating water retention, soon feeding the broken down nutes for a balance diet. MG kills the Microbes, weakens the plants immunity & cell structure, etc. Not one aspect of MG promotes anything Healthy for the plant or soil. Also, Organic growing is not more expensive in the long run. Once soil is provided with the proper nutes, etc; it gets healthier each year with less requirements. It GROWS... It MULTIPLIES. The Microbial Life, the Fungi's & Bacteria, that feeds & protects the plants. The best pot in the world is just a by-product of having a healthy soil, unlike chem infested soils, which is a dead zone. My 2¢
