        (1) The elements Nitrogen, Phosphorus, and Potassium are considered the important
nutrients for strong growth. Calcium can be used to control the pH.
Calcium is not added to the soil as a nutrient, but rather to balance the pH of the soil.
Continued use of Nitrogen, Phosphorus and Potassium will lower the pH of the soil. This can be
rectified by adding some Calcium or good old vinager.

         (2) NITROGEN (N)
Nitrogen together with phosphorus and potassium are the main ingredients in normal fertilizers.
All proteins, also the ones in the plant, contain nitrogen. All enzymes (these are matters that
regulate the character and speed of the chemical reactions in the plant) are proteins.
Especially chlorophyl with which the plant produces sugars (with the help of light, water and
carbon dioxide) contain many proteins and therefore a lot of nitrogen. From the previous you
might understand why nitrogen is such an important nutrient for the plant. When a plant receives
too little it is first shown by the color.
 Because so much nitrogen is needed to make chlorophyl, a shortage will be noticed here first.
The plant will become very light green. This fading starts first with the older leaves. BUT: when
there is insufficient light it is of no use for the plant to make chlorophyl that also gives this light
green color.
When this is the cause however, the leaves also tend to "reach out for the light" in their shape.
With a nitrogen shortage you don't see this. Also with a nitrogen shortage the plant becomes
more susceptible to mycosis. With too much nitrogen the opposite will happen. The plant
becomes unnaturally dark green and the growth stagnates. Adding ample Nitrogen ensures fast
lush growth, enabling a Cannabis plant to outgrow almost any other plant.

       (3) PHOSPHORUS (P)
Just like nitrogen, phosphorus is important for protein chemistry of the plant, especially in the
regulation processes. A shortage of it is expressed as slow growth and sometimes a purple
coloring of the whole leaf. The chance of a phosphorus shortage is small with the right nutrition.
An excess is more likely to occur, especially with substrate cultivation, because phosphorus can
accumulate in the root environment. When this happens the plant can't absorb enough zinc so the
symptoms are similar as with a lack of zinc. (see Zn).

 Cannabis' need for phosphorus is the greatest during the seedling and flowering stages of it's life
cycle.

       (4) For the healthy development of a plant a number of nutrients are indispensable. The
following elements are necessary: carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur,
potassium, calcium, magnesium, iron, manganese, copper, zinc, molybdenum, borium and
chlorine. Carbon is being absorbed through carbon dioxide. (In carbon dioxide one particle of
carbon is attached to two particles of oxygen). Hydrogen and oxygen are mainly absorbed by
means of water. (In water two particles of hydrogen are attached to 1 particle of oxygen).




       (5) POTASSIUM (K)
This nutrient is especially important in the humidity regulation. With a potassium deficiency,
symptoms of burning occur. With too much potassium there will be a shortage of calcium and
magnesium. (see Ca and Mg). During the flower period the plant requires more potassium.
 To grow to a large size, marijuana requires a steady supply of THE PROPER nutrients at THE
PROPER time which should be added to the water on a regular basis.



        (6) The amount of nutrients to add to the water depends on the size of the plant, the size
of the pot, and the general condition of the soil. (sometimes weights indicate if you need water)

      (7) Always add water when you add any nutrients or fertilizer to the soil. It is
recommended that you dissolve the fertilizer in the water before watering the plant. (outdoors !
only when the climate is too wet, spread nutrients on top of soil)

      (8) Adding more nutrients than a plant requires will toxify the soil thereby harming plant
growth and development. (osmosic pressure)

A too high EC will produce a too high osmotic pressure around the roots. Osmosis? A liquid
moves, according to physics, in the direction of the strongest solution. If the solution outside the
plant is stronger than inside, then the plant empties itself (simply said). This emptying of the
plant can be noticed in practice as a so called burning of the leaves. (When leaf blades curl down
they are trying to conserve water).

       (9) Foliar feeding, or spraying the leaves with a fertilizer solution, is an ideal way of
fertilizing large plants with nutrient deficiencies.
Whenever all the leaves appear a bit pale each day…( you maybe out of Mg ? use Epson-Salt)

       (10) a) MAGNESIUM (Mg)
Magnesium is necessary for the production of chlorophyl. With a deficiency the plant will
yellow between the veins, initially in the older (strange enough not in the very oldest) leaves.
Too much would make the growth stagnate, but this is rarely the case with proper cultivation
methods.
               (b)CALCIUM (Ca)
This nutrient is "built-in" the cell walls and membranes of the plant cells. A shortage might occur
in the leaves when the relative humidity is too high (and they cannot evaporate enough water),
and with a potassium overdose. With a lack of calcium, the young leaves and new buds die. The
plant also becomes very susceptible to mycosis. If the calcium deficiency is being caused by a
too high humidity, the entire crop can be ruined in no time through molding.

       (11) To save overfertilized plants, the soil can be leached by removing the top few
centimeters and overwatering with lukewarm water.

       (12) Although healthy, strong growing plants love a steady supply of nutrients, you
should never fertilize them every day.

       (13) A plant growing in a poor soil, low in nutrients will develop better than a plant
growing in overfertilized soil. Although Cannabis does not grow well in a soil with a low
nutrient content, this is preferable to a soil that has been toxified by over-fertilization.

       (14) Although Carbon Dioxide cannot be classified as a true nutrient, it can been used to
increase growth during the vegetative stage.

      (15) A soil rich in Nitrogen will increase internodal growth in the stems of developing
young marijuana plants.

      (16) Urine is an excellent source of Nitrogen for marijuana plants, but as it is too
concentrated to apply directly, it should always be diluted with water.

(17) Unless the soil is poor in nutrients, a young seedling growing in a large pot doesn't require
any fertilizing for the first few weeks of it's life.


         (18) Nitrogen can be positively correlated with higher potency and increased growth, and
it is the most influential nutrient available to the grower. (electro-conductivity law)

       (19) Organic fertilizers are less concentrated than chemical mixes, and as the nutrients are
released more slowly, there is less chance of toxifying the soil.

       (20) A typical program of fertilization may be to fertilize after the fifth week of growth,
and then every two weeks thereafter until flowering.
        (21) It is always better to fertilize your plants more often with a more diluted solution,
than to give them concentrated doses at longer intervals.

        (22) Always make sure that the fertilizer is completely dissolved in the water before you
apply it to your plants.

       (23) It takes less Nitrogen than other nutrients to toxify the soil, and hence there is less
margin for error when using it as a fertilizer.
