Mineral Elements/Nutrient Mixing Directions

There are 20 Mineral Elements

 

Macronutrients are required in large amounts
Carbon C Component of all organic compounds
Oxygen O supplied by air &water
Hydrogen H  
Nitrogen N Part of chlorophyll, amino acids, proteins
Phosphorus P Used in photosynthesis and almost all aspects of growth
Potassium K Activates enzymes, used in formation of sugar and starch
Calcium Ca Used in cell growth and division, part of cell wall
Magnesium Mg Part of chlorophyll, activates enzymes
Sulfur S Part of amino acids and proteins

 

Micronutrients are required in trace amounts
Boron B Affects reproduction
Chlorine Cl Aids in root growth
Copper Cu Used in clorophyll, activates enzymes
Iron Fe Used in Photosynthesis
Manganese Mn Part of chlorophyll, activates enzymes
Sodium Na Used for water movement
Zinc Zn Part of enzymes, used in auxins
Molybdenum Mo Used in nitrogen fixation
Nickel Ni Liberates Nitrogen
Cobalt   Fixates Nitrogen
Silicon   Makes tougher cell walls: enhances heat and drought tolerance

6 Pack Nutrient Mixing Directions

Mix each nutrient separately following the order of appearance on the list until all are added. Test pH after nutrients are added. (pH will drop about a point.) Ideal pH reading is 6.5. Once every week to two weeks pump out your reservoir and re-mix the nutrient solution. This is a good time to leach your system by running on straight water for six to eight hours or until the EC rises to approximately 1000 mmho/cm. A manual leach may be done by flushing with straight water during the pumping out cycle. Plants use more water than nutrient. In between nutrient changes top up the reservoir with pH balanced (6.5) water thereby avoiding a concentration.

Herbs in General
mixing directions based on teaspoon/10 litre (for small quantities only)

Veg Bloom
CaNO3 2 1/2 2
K2SO4 1/6 1
KNO3 5/6 none
KH2PO4 5/8 3/4
MgSO4 2 3/4 2 7/8
TE 1/5 1/6

A & B concentrate (stock solution)
for mixing directions based on teaspoon/10 litre

When using an EC Meter it’s helpful to form a concentrate that is easily administered to the nutrient solution to keep EC at optimum level. To achieve a 100x concentrate mix ten times the amount shown of each A’s and B’s in two separate one litre containers: A = 1st, 3rd and 6th on the list, B = 2nd, 4th and 5th on the list.

A & B concentrate (stock solution)
for mixing directions based on grams/ltr

When using an EC Meter it’s helpful to form a concentrate that is easily administered to the nutrient solution to keep EC at optimum level. To achieve a 100x concentrate mix ONE HUNDRED times the amount shown of each A’s and B’s in two separate one litre containers: A = 1st, 3rd and 6th on the list, B = 2nd, 4th and 5th on the list.

The calculations

  • Determine the size of the tank.

  • Determine what the ppm of the element is to be in the final mix.

  • Go to the chart and select number of gallons.

  • Divide the goal ppm by corresponding number.

  • The answer is the number of ounces of nutrient to use.

Example

  1. You have determined that you have a 50 gallon tank and you need 125 ppm(goal) of calcium added. You don’t want to add any more nitrate so the compound you choose is calcium chloride. You next find that one ounce in a 50 gallon tank will add 27 ppm calcium. Next divide the goal by this number. 125/27 = 4.63 oz. = about 1/2+ cup.
  2. You have determined that you have a 150 gallon tank and you need 140 ppm(goal) of calcium added. You need more nitrate so the compound you choose is calcium nitrate. You next find that one ounce in a 50 gallon tank will add 33 ppm calcium and 23 ppm nitrate. Next divide the goal by this number. 140/33 = 4.25 oz. Since you need it for 150 gallons, you will have to multiply by 3. So 4.25 * 3 = 12.75 oz = about 1 1/2 cup. If you want to determine how much nitrigen you are adding, simply multiply the amount added to 50 gallons (4.25) by the ppm of nitrate from one ounce(23) which equal 115 ppm nitrate increase in the 150 gallon mixture when 12.75 oz of calcium nitrate have been added.

Conversions

1 Tbs = 3 tsp = 1/2 oz. = .5 oz

2 Tbs = 1oz = 1/8 cup

4.5 oz = 1/2 cup = .5 cup

Anything above 1/2 cup should be weighed. One cup of most compounds weigh about 9 oz.

  • The cup is for liquids. A liquid ounce is measured by volume. A dry ounce goes by weight.
