Macro Nutrients for Cannabis
What are considered as Macro-Nutrients are the 3 main nutrients necessary for a healthy plant. It’s important to note that all these nutrients are mobile one’s
The 3 main nutrients are:
Nitrogen (N)
Marijuana looooves Nitrogen and requires high levels of it during the vegetative stage but much lower levels once the plant enters the flowering stage.
Nitrogen is a nutrient that easily washes away and needs to be replace regularly, especially during vegetative growth.
If there’s an excess of Nitrogen when harvesting the plant the buds won’t have as good of a taste and won’t burn well. It’s important to flush well your plants before harvest.
The Purpose of Nitrogen
Nitrogen regulates the cannabis’s ability to make proteins essential for new protoplasm in the cells.
Electrically charged nitrogen allows the plant to tie proteins, hormones, chlorophyll, vitamins and enzymes together. Nitrogen is essential for the production amino acids, enzymes, nucleic acids, chlorophyll and alkaloids.
This important nutrient is mainly responsible for leaf and stem growth as well as overall size and vigor.
Nitrogen is most active in young buds, shoots and leaves. Ammonium (NH4+) is the most readily available form of nitrogen.
If you use this, be careful not to use too much since it can easily burn the plants.
The Nitrate form of nitrogen is much slower to assimilate than ammonium, and will release much slower in the soil. Hydroponic fertilizers use this slower-acting nitrogen compound and mix it with ammonium.
Phosphorus (P)
Cannabis uses the phosphorus during all stages of it life since it has different purposes at each stage. From root development during the vegetative stage to bud growth during the flowering stage, phosphorus is one of those extremely important nutrients.
As is the case with Nitrogen, Phosphorus is a Mobile element, meaning that the plant can reallocate it where ever it’s needed.
Purpose of Phosphorus
Phosphorus is nessary for photosynthesis and provides a mechanism for the energy to transfer within the plant. It’s also one of the components of DNA, it’s also associated with overall vigor, resin and seed production.
The Highest concentrations of phosphorus are found in the root-growing tips, growing shoots and vascular tissue.
Potassium (K)
Potassium is used at all stages of growth. Soils with a high level of potassium increase a plant’s resistance to bacteria and mold.
Purpose of Potassium
Potassium helps combine sugars, starches and carbohydrates which is essential to growth by cell division. It increases the chlorophyll in the foliage and helps to regulate the stomata openings so plants make better use of the light and air.
Potassium is essential in the accumulation and translocation of carbohydrates. It’s necessary to make the proteins that augment the oil content and improve the flavor in cannabis plants.
It also encourages strong root growth and is associated with disease resistance and water intake.
