Nutrients can broadly be categorized by micro or macro and in terms of their mobility; either mobile or immobile. Mobile nutrients are those that the plant can move around to where they are most needed while immobile nutrients cannot be relocated. This mobility of the nutrient affects where [[Symptoms of bad health|symptoms of deficiency]] (or excess) can occur on a plant.
==
Most fertilizers on the market come in 2 categories; general nutrients for the vegetative stage and flowering (or bloom) nutrients for the flowering stage of growth. Vegetative nutrients contain large amounts of Nitrogen and flowering nutrients contain mostly Potassium and Phosphorus. There are also solutions that provide micronutrients, sugars, and acids to boost growth even further.
== Common Fertilizer Ingredients ==
=== Macro Nutrients ===
Macronutrients are those nutrients that Cannabis requires in large amounts, the three main nutrients are Nitrogen, Phosphorus, and Potassium (often written as NPK). They typically come from the soil and are crucial throughout the plant's lifespan, although in differing ratios. Vegetating plants require more Nitrogen and less Phosphorus and Potassium, while flowering plants demand much less Nitrogen and much more Phosphorus and Potassium during the flowering stage.
A rough guide NPK ratio:

==== Nitrogen ====
Required for the production of most plant cells as well as chlorophyll, used in photosynthesis.
==== Phosphorus ====
Essential for the flowering period, Phosphorus strengthens the plant and is used for root development.
==== Potassium ====
Required for root development. Potassium also regulates the opening and closing of [[Anatomy of Cannabis#Stomata|stomata]] for [[Plant processes#Gas exchange|gas exchange]].
Cannabis also obtains Oxygen, Carbon, and Hydrogen from water and air.
=== Micro Nutrients ===
Micronutrients are the elements that are needed in much smaller quantities than macronutrients, however, this does not make them any less important.
=== Silica ===▼
▲==== Silica ====
Silicon dioxide or "Silica" can increase stem diameter and boost chlorophyll production.<ref>https://www.maximumyield.com/simply-silica/2/1077</ref>
==== Magnesium ====
A mobile nutrient required for the creation of chlorophyll in a plant, a requirement of [[Plant_processes#Photosynthesis|Photosynthesis]].
==== Calcium ====
An immobile nutrient that is required for the creation of strong cell walls.
==== Boron ====
Similar to calcium, boron is required for strong cell walls.
==== Copper ====
Copper is used in photosynthesis by helping metabolize proteins and carbohydrates.
==== Iron ====
Iron supports the function of chloroplasts.
==== Manganese ====
==== Sulphur ====
==== Zinc ====
=== Acids ===
==== Amino Acids ====
==== Humic and fulvic acids ====
=== Microbes ===
Bascillus microbes.
=== Fungus ===
==== Mycorrhizal Fungi ====
Some fungi can live symbiotically with the plant's root system, they consume some glucose created by the plant while increasing nutrient uptake. Some soil mixes come with mycorrhizae already added, you can buy it separately and combine it with your medium, or it can be added to the medium in the hole where a plant will be transplanted.
