Best Cannabis Nutrients: Top 10 Reviews for Marijuana Plants

0

Whether you’re growing cannabis for your use or commercial purposes, you have probably realized that there is more to it than sowing your seeds in good soil, watering them now and then, and having grow-lights.

Cannabis plants, just like any other plant, require nutrients to survive and thrive. You want your plants to produce flavorful and aromatic buds, so you need to invest in the right nutrients.

Feeding marijuana, however, is a nuanced activity. The macro and micronutrient requirements vary between strains at different stages of growth. Additionally, the various phenotypes of the same strain may have different nutrient requirements. Of all the critical environmental factors in the cultivation of marijuana, nutrients are entirely in the hands of the farmer. If the grower makes errors, the plants start to show subtle signs followed by withering.

To avoid over or under fertilizing the cannabis plants, you need to get your nutrients right from the beginning. The process requires administering the right proportions at the right time. Here are the best marijuana nutrients and products you should feed your plants.

What to Know about Cannabis Nutrients – Buyer’s Guide

Your cannabis plant requires the right nutrients to thrive, just like any other plant. Here are some of the essential things you should consider when buying fertilizers for your plant.

The NPK Ratio

The three macronutrients – Nitrogen, Phosphorous, and Potassium – are the base of marijuana growth. You will want to apply NPK base nutrients in different quantities for the complete cannabis lifecycle.

Vegetative Growth Phase

During the early stages of the cannabis life cycle, nutrient requirements are minimal. The plants require a high N feed, so most growers favor a 3:1:1 NPK ratio. The ratio satisfies the needs of virtually all cannabis strains. It’s not just about nitrogen, but N levels should be more than P and K until bloom.

Nitrogen additives are not required for soil growers because the soils naturally contain enough fertilizers for the first month of growth. Just add water and look out for nutrient lockouts.

Flowering Phase

The transition to flowering stage causes a swing in the macronutrient requirements, which calls for adjustment of the NPK ratio.

Until mid-bloom, a 1-3-2 NPK formula should be sued and succeeded by a 0-3-3 ratio until late bloom.

Finally, add a flush of water or flushing solution for flavor.

The P&K dictates the size of the bud. This is why you will want to reduce the N quantities and increase the P&K quantities at the same time. Too much N can spoil the sinsemilla and the taste of the buds, resulting in a rough stash. You should avoid the N nutrient in the last ten weeks before harvest.

Best Cannabis Nutrients

Like any other plant, cannabis requires some essential nutrients to grow and produce a high yield of buds. The plants need a large number of macronutrients, lesser amounts of secondary nutrients, and trace amounts of micronutrients. There are about 20 essential nutrients that are necessary for your weed to germinate, grow, flower, and produce seeds.

Macronutrients

Macronutrients are in the group of nutrients required in large quantities. Some of the macronutrients are natural in the soil, while others you will need to add to the soil. Some elements – i.e., Oxygen, Hydrogen, and Carbon – do not count as macronutrients because they are so abundant. However, they are still necessary for large amounts. The ones that you can add to the soil are Nitrogen, Phosphorous, and Potassium, often known by their volumes in NPK ratios.

Generally, Nitrogen is necessary for the growth of foliage. Phosphorous helps the development of root, flower, and seed. Potassium is essential for the overall health of the plant. As explained above, however, cannabis requires different amounts of macronutrients depending on the stage of development.

Secondary Nutrients

Most sources classify secondary nutrients as macronutrients. However, plants don’t require these secondary nutrients in as large of quantities as macronutrients. The amounts are significantly higher than those of micronutrients, so they can’t be classified together either.

Secondary nutrients include Magnesium, Calcium, and Sulfur. These nutrients are essential in the growth of cannabis, but they may be unavailable if you fail to maintain proper pH levels.

The nutrients perform crucial functions in cannabis growth, such as promoting root growth. Calcium promotes transportation and absorption of other nutrients. Magnesium makes chlorophyll, which plants consume as food. Sulfur transports chlorophyll and aids in metabolism and transpiration. Lesser quantities of these nutrients are necessary, but this doesn’t imply they are less critical.

Micronutrients

This group represents minerals and elements that are not highly available on Earth and are also not required in high quantities by cannabis plants. However, they are still necessary. They include Zinc, Copper, Iron, Boron, Manganese, and Molybdenum. Like other nutrients, they have a unique function to serve the plant.

Here are some of the functions:

  • Zinc: Used in the development of leaves, branches, and stems. It is necessary for mature and maturing cannabis plants.
  • Copper: Helps with the growth of plant proteins and is used to strengthen branches and stems.
  • Iron: Essential for chlorophyll production. Yellowing of leaves might show iron deficiency
  • Boron: Aids in the development of root tips. It also promotes the transportation of sugars and the absorption of Ca.
  • Manganese: Supports chlorophyll production and photosynthesis. It also helps with enzyme interactions.
  • Molybdenum: Helps process nitrogen.

Feeding Schedule

Generally, the quantity of fertilizer you supply to your cannabis plants depends on the size of the plant and the growing stage. You can add fertilizer to the water before you introduce it to the plants, which gives the plants a more balanced ratio.

You should only feed fertilizers and nutrients to the plants a few times or when the plants start looking like they lack nutrients.

The feeding schedule of cannabis depends on whether you are growing outdoors or indoors. If the plants are outdoors, you will need to give them more nutrients because they grow taller, thus require high Nitrogen quantities. If the plants are grown indoors, they will have a grow-light link set up, so they don’t need as many nutrients.

Organic vs. Synthetic Nutrients

When shopping for nutrients for your marijuana, you will often face a decision: whether to choose synthetic or organic fertilizers. There are benefits and demerits of using both.

  • Synthetic: Also known as chemical fertilizers, synthetic nutrients often have quick results. They act quickly and help your plants to show vigorous growth in a short time. They are the solution to bringing higher yields in a short time. These fertilizers are also active in hydroponic systems. They keep the system running without contamination and increase the potency of crops. The efficiency may vary, however, depending on the strain and growing medium, among other factors.
  • Organic Nutrients: On the other hand, organic nutrients are all-natural and do not affect the ecology. They are effective when cannabis is grown in the soil. They give the plants a superb taste and aroma. However, when used in a hydroponic system, they can cause clogging or promote the growth of unwanted plants.

Watering and pH Levels

Besides nutrients, there are other factors to consider when it comes to growing marijuana. You need to think about water and pH levels.

Water pH is especially an essential factor if you are growing in a hydroponic system. The first red sign when it comes to pH is when you notice that the plants are displaying particular deficiency signs despite supplying them with enough fertilizers. These deficiencies could be a result of your water pH not being satisfactory to the plant, which reduces the ability of the plant to absorb nutrients.

Hydroponics requires an alkaline medium, so the pH must be between 5.5 and 6. If you are growing in soil, pH should be a bit more acidic; between 6 and 7.

Make sure you water the plants regularly but be careful not to over-water. Too much water with little airflow can cause roots to rot. You’ll have to experiment to reach the optimal amount of water because several variables can affect it. The optimal water quality depends on the climate, environment, and strain of cannabis.

Final Thoughts

As with growing any plant, growing marijuana requires close attention to the nutrients that you supply your crops. If grown in a hydroponic system, marijuana can even be fussier than other types of plants because it doesn’t have access to the best cannabis nutrients.

The guide above should help you grow healthy plants. You can perfect your growth process by purchasing any of these materials and getting to work.
