5 essential base nutrients for growing cannabis

Nutrients play a critical role in providing essential nourishment to plants. Without the proper nutrients, plants would not be able to grow healthy and strong, and cannabis is no exception. 

In this article, we’ll discuss the 5 essential nutrients needed for your cannabis plants to produce dank terpene-rich buds. 


There’s a reason we are starting off with Nitrogen. Because it is absolutely one of the most essential nutrients for the cannabis plant. What makes this nutrient so important? Well, Nitrogen is a vital part of chlorophyll, which is needed in the process of photosynthesis. Healthy plants contain 3-4% nitrogen in their tissues. Which is a much higher concentration compared to other nutrients. Having the proper amount of Nitrogen in your soil or grow media is needed for your cannabis plants to be able to feed, grow, and produce healthy harvests. 


Another base nutrient is Phosphorus which aids in supporting the growth of the plant. It’s also the only base nutrient found in every living plant cell. So as you can see it’s pretty crucial because Phosphorus functions as a stimulant to aid key biological responses needed for new cannabis growth. These biological responses include photosynthesis, metabolism, and nutrient absorption. So in fact, the cannabis plant uses Phosphorus in every phase of plant development making it an essential base nutrient.


Potassium is another important base nutrient in the cannabis plant. However, unlike Nitrogen, this nutrient is not as present in the plant tissue because Potassium is used by the plant to interact with Nitrogen and works to aid in the plant’s production of proteins and amino acids. 

These proteins are essential for improving the durability and strength of the cannabis plant. Potassium also works in conjunction with Phosphorus to boost the overall root structure giving it more strength and protection against elemental damage.


Next we’ve got Calcium which is found in all phases of the growth stages and serves multiple key functions. Calcium works to improve the transfer of nutrients and assists with helping the plant to absorb other nutrients. When a cannabis plant has a calcium deficiency, it quickly leads to other issues because if the plant’s calcium is low, it cannot absorb nutrients properly. 


Last but not least, you have Magnesium which is actually one of the most important nutrients for your cannabis plant. Cannabis plants need to use a lot of this nutrient, in fact Magnesium is pretty much used in every stage of plant life. Magnesium also plays a key role in transforming light into energy. This nutrient affects the cannabis plant’s ability to absorb light, creating the plant’s food source. Ie. Sugars and carbohydrates.
