Answer 2

Google led me to Wikipedia which says;

Plants require specific elements for growth and, in some cases, for reproduction.

Major nutrients include:

    * C = Carbon 450,000 ppm

    * H = Hydrogen 60,000 ppm

    * O = Oxygen 450,000 ppm

    * P = Phosphorus 2,000 ppm

    * K = Potassium 10,000 ppm

    * N = Nitrogen 15,000 ppm

    * S = Sulfur 1,000 ppm

    * Ca = Calcium 5,000 ppm

    * Mg = Magnesium 2000 ppm

Minor Nutrients:

    * Fe = Iron 100 ppm

    * Mo = Molybdenum 0.1 ppm

    * B = Boron 20 ppm

    * Cu = Copper 6 ppm

    * Mn = Manganese 50 ppm

    * Zn = Zinc 20 ppm

    * Cl = Chlorine 100 ppm
