Best Guide for Cannabis Fertilizers & Nutrients

If you’re growing cannabis, it’s safe to say that you want to produce the best cannabis. Professional cannabis fertilizer is essential. Growing healthy, high-yielding cannabis plants requires ensuring they have the nutrients they need to absorb.

To make plants grow as healthy as possible. They need three major nutrients: nitrogen (N), phosphorus (P), and potassium (K). And some other micronutrients and minerals.

These are usually found on cannabis fertilizer labels and are displayed in numerical order corresponding to the nitrogen, phosphorus, and potassium content ratio of the fertilizer. Let’s understand the role of each nutrient to better understand the actual benefits of using weed fertilizer.

Cannabis has a relatively simple growth cycle, divided into three stages:

Seedling Stage: Cannabis seedlings are very fragile and “burn” easily in nutrient-rich soil. We do not recommend feeding during the seedling stage.

Vegetative Stage: The roots begin to develop and more leaves begin to grow. It’s time to start feeding them the nutrient solution of your choice. In the nutritional stage, high nitrogen, medium phosphorus, and high potash fertilizer are required.

Flower Stage: Nitrogen, phosphorus, and potassium levels were different in the vegetative and flowering stages. It is important to note that low nitrogen, high phosphorus, and high potassium are needed at the flowering stage.

Cannabis Fertilizer for Bloom

For cannabis growers, one of the most critical periods of plant growth is the flowering period. The flowering period is about eight weeks.

There are five steps, including transition, primary buds development, buds growth, buds maturation, and harvest of buds.

During the flowering process, you need to provide the right amount of nutrients to the plant in order to obtain high-quality buds.

The essential nutrients for the growth of cannabis are nitrogen (N), phosphorus (P), and potassium (K). When weed begins to flowering, they must gradually increase the concentration of P and K, while greatly decreasing the concentration of N. 

This is why there are two kinds of special cannabis fertilizers for vegetative growth and flowering.

Besides, Some “secondary” nutrients are also essential for weed, such as magnesium (Mg), calcium (Ca), and sulfur (S), but the using quantity is much smaller than NPK.

Cannabis also needs trace elements to reach its full potential, which are copper (Cu), boron (B), zinc (Zn), chlorine (Cl), iron (Fe), manganese (Mn) and molybdenum (Mo). The amounts of these trace elements required by hemp are exceedingly small and are often mixed into fertilizers or soil.

Seaweed Extract Effect for Cannabis

The health of the cannabis plant is a very important part of cannabis cultivation. This is why a great deal of consideration and in-depth research are required to understand the best nutrients that can promote plant health. The seaweed extract in particular is rich in many beneficial nutrients that can help your cannabis reach its optimal size and grow healthy.

Fresh seaweed contains calcium, magnesium, boron, sulfur, and an unlimited amount of macro and micronutrients absorbed from the ocean.

In addition, seaweed helps retain moisture in the soil, thus reducing watering cycles, while still encouraging beneficial bacteria that help plants break down organic matter and obtain essential nutrients.

It also acts as a defense mechanism against fungi, bacteria, and viruses by producing certain compounds that are effective against them. 

Applying seaweed to plants promotes cannabis germination while regulating the pH of the soil. It also promotes cannabis metabolism by increasing trace elements in the soil, while improving the soil structure for easy access to nutrients and root growth.

Soil Amendments for Cannabis Growth

Good soil and nutrients are the basis for growing the best cannabis. The physical condition of the soil is a major factor directly limiting the health and vitality of cannabis. It’s especially important for weed when soil fertility affects weed yields. When soil conditions are poor, water intake, root development, and aeration are restricted.

When soil amendments applied to the soil, it provides a number of benefits. The most common is to improve the soil structure. It can increase the texture of the soil and keep it loose, allowing cannabis to absorb more nutrients and water.

Common organic soil amendments for cannabis: Worm castings, Crustacean meal, Bat guano, Bone meal, Rock dust, Kelp meal, Compost, Mycorrhizal fungi, Trichoderma harzianum.
