The best nutrients for growing cannabis depend on the stage of growth and the specific needs of the plant. In general, cannabis plants need a balanced mix of primary nutrients (nitrogen, phosphorus, and potassium) and secondary nutrients (calcium, sulfur, and magnesium) as well as micro-nutrients (iron, zinc, copper, manganese, boron, etc.).
During the vegetative stage, cannabis plants need higher levels of nitrogen to promote healthy leaf growth. A fertilizer with a balanced NPK ratio of 3-1-2 or 2-1-3 is generally recommended during this stage.
During the flowering stage, cannabis plants need higher levels of phosphorus and potassium to promote healthy bud development. A fertilizer with a balanced NPK ratio of 1-3-2 or 1-2-3 is generally recommended during this stage.
It’s also important to consider the specific growing conditions and the medium used. For example, if you are growing cannabis in soil, you may need to add additional calcium, sulfur, and magnesium to the soil to ensure your plants have access to all the essential nutrients. If you are growing cannabis in hydroponics, you will need to provide your plants with a balanced nutrient solution that provides all essential nutrients.
It’s important to note that not all cannabis plants have the same nutrient requirements, and it’s always best to consult with a specialist or conduct research to determine the specific nutrient requirements of your plants. Additionally, some cannabis cultivars have different nutrient requirements and it’s important to get familiar with what specific cultivar you are growing.
In summary, cannabis plants need a balanced mix of primary and secondary nutrients as well as micro-nutrients. The specific mix of nutrients will depend on the stage of growth, the specific needs of the plant, and the growing conditions. It’s best to consult with a specialist or conduct research to determine the specific nutrient requirements of your plants.

Top 5 Nutrients to buy for Growing Cannabis
Should you always grow Cannabis with nutrients
Nitrogen(N):
Nitrogen plays a crucial role in the growth and development of cannabis plants. Nitrogen is essential for the growth of leaves and stems, and it is a key component of chlorophyll, the molecule that allows plants to convert light energy into chemical energy through photosynthesis. Adequate levels of nitrogen are necessary for the plant to produce healthy green leaves and strong stems, which are needed to support the growth of buds and flowers. Nitrogen is also important for the production of amino acids, which are the building blocks of proteins. These proteins are necessary for the growth and development of new cells and tissues, as well as for the repair of damaged tissues.
However, it is important to note that too much nitrogen can also be detrimental to the plant, causing the plant to grow large and lush leaves at the expense of buds and flowers. Therefore, it is important to monitor the nitrogen levels in the soil or nutrient solution and adjust as necessary to achieve the optimal balance for cannabis growth.
Phosphorus(P):
Phosphorus is essential for root growth and development, and it helps plants to develop strong and healthy root systems. This is important for cannabis plants, as a strong root system helps the plant to absorb water and nutrients more efficiently, which in turn helps to promote overall plant health and growth.
Phosphorus also plays a key role in the development of buds and flowers, it promotes the development of strong stems, and it helps to increase the size and density of buds and flowers. Adequate levels of phosphorus are necessary for the plant to produce high-quality buds and flowers, and it is particularly important during the flowering stage of growth.
Phosphorus also helps the plant to defend itself against diseases and pests by strengthening the cell walls and increasing the production of enzymes and other natural defense mechanisms.
It is important to monitor the phosphorus levels in the soil or nutrient solution and adjust as necessary to achieve the optimal balance for cannabis growth. As with Nitrogen, too much Phosphorus can be detrimental to the plant, can cause the plant to produce fewer buds, and can also lead to nutrient lockout (when other nutrients become unabsorbable by the plant due to an excess of phosphorus)
Potassium(K)
Potassium is essential for overall plant health and disease resistance, and it helps to regulate many of the plant’s physiological processes.
It helps the plant to regulate water uptake and distribution, and it helps to maintain the proper balance of water and nutrients in the plant’s cells. This is important for cannabis plants, as it helps the plant to conserve water and resist wilting, which can be particularly important in hot and dry growing conditions.
Known to also plays a role in the process of photosynthesis, which is the process by which plants convert light energy into chemical energy. Potassium helps to maintain the proper balance of chlorophyll, the molecule that allows plants to photosynthesize, which helps to promote overall plant health and growth.
It also helps the plant to defend itself against diseases and pests by strengthening the cell walls and increasing the production of enzymes and other natural defense mechanisms.
Potassium is also involved in the development of buds and flowers, it promotes the development of strong stems, and it helps to increase the size and density of buds and flowers. Adequate levels of Potassium are necessary for the plant to produce high-quality buds and flowers, and it is particularly important during the flowering stage of growth.
As with Nitrogen and Phosphorus, it is important to monitor the potassium levels in the soil or nutrient solution and adjust as necessary to achieve the optimal balance for cannabis growth. An excess of potassium can lead to nutrient lockout, and can also cause the plant to produce fewer buds.
Nitrogen is necessary for the growth of leaves and stems, phosphorus is important for root growth and flower and fruit development, and potassium helps with overall plant health and disease resistance. A proper balance of these nutrients is important for healthy plant growth.
Micronutrients:
In addition to the primary macronutrients (nitrogen, phosphorus, and potassium) that plants need to grow, there are also several essential micronutrients that are used for growing cannabis. These include:
- Calcium (Ca): essential for cell growth and division, and for the development of strong roots and stems.
- Magnesium (Mg): plays a role in photosynthesis and is necessary for the production of chlorophyll.
- Sulfur (S): necessary for the production of proteins and enzymes, and for the development of healthy roots, stems, and leaves.
- Iron (Fe): essential for the production of chlorophyll, and for the development of healthy leaves and stems.
- Manganese (Mn): plays a role in photosynthesis and is necessary for the production of proteins and enzymes.
- Copper (Cu): involved in the production of enzymes and other proteins, and helps to strengthen the plant’s immune system.
- Zinc (Zn): necessary for the production of hormones and enzymes, and for the development of healthy roots, stems, and leaves.
- Boron (B): helps to regulate the uptake and use of other nutrients, and is necessary for the development of strong roots and stems.
- Molybdenum (Mo): plays a role in the process of nitrogen fixation, and is necessary for the production of enzymes and proteins.
It’s important to note that cannabis plants may require different amounts of micronutrients depending on the stage of growth, the medium being used, and the specific strain. Therefore, it’s important to monitor the levels of all essential micronutrients and adjust as necessary to achieve optimal growth for cannabis plants.
These elements are essential for the growth and development of plants, and they play a critical role in various plant functions such as photosynthesis, protein synthesis, and water uptake.

Should You Always Use Cannabis Fertilizer?
Cannabis plants can grow and produce buds without the use of fertilizer, but using a fertilizer can enhance the growth, yield, and overall health of the plant. Different types of fertilizers, such as those high in nitrogen, phosphorus, or potassium, can be used to provide specific nutrients that the plant needs at different stages of growth.
It’s also important to keep in mind that cannabis plants grown in soil will naturally get the nutrients they need from the soil, whereas if you are growing in a hydroponic setup, you will need to provide your plants with the essential nutrients through fertilizers or nutrient solutions.
In summary, while cannabis plants can grow without the use of fertilizer, using a fertilizer can enhance the growth, yield, and overall health of the plant. However, it is important to use the right type and amount of fertilizer and consult a specialist or conduct research before applying any fertilizer to your cannabis plants.
