== Macro Nutrients ==
Macronutrients are those nutrients that Cannabis requires in large amounts, the three main nutrients are Nitrogen,
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.
Cannabis also obtains Oxygen, Carbon and Hydrogen from water and air.

* Phosphorus
* Potassium
* Oxygen
* Carbon
* Hydrogen
== Micro Nutrients ==
The most common deficiencies that I have come across are Magnesium and Calcium. There are liquid nutrient solutions (e.g. CalMag) that provide both. This should be added to the soil before planting if possible. Alternatively, one can use organic additions (e.g Dolomite Lime) but note that some sources will change the pH of the medium.
Using too many nutrients can create a nutrient burn on the leaves, primarily on the [[Anatomy_of_Cannabis#Apex|apex]]
== Sources of nutrients ==
Nutrients can be provided to a cultivar via concentrated liquid solutions, organic materials, and even other organisms living in the growing medium.
