Growing marijuana, whether for commercial or personal use, takes a lot more than just good soil, adequate watering, and sunlight. A lot goes into a single weed plant, the most important of them all being nutrients. You need to use the best nutrients for marijuana plants for you to get aromatic, flavorful buds. We compiled the best marijuana nutrients you can use to ensure your plants thrive and yield the best buds possible.
Before jumping on a single nutrient you have heard about everywhere, you need to be well versed in a couple of things. Some of these things include the type and amount of nutrients your marijuana needs, the best marijuana nutrients for the soil, and the nutrient requirements your marijuana needs at its different growth stages.
Types of Cannabis Nutrients
These are the several nutrients your plant needs for its everyday growth:
They refer to a group of nutrients needed in large quantities. There are naturally occurring macronutrients and some that you will need to add to the soil. These include Phosphorus, Nitrogen, and potassium, commonly used in the NPK ratio.
Nitrogen is used for growth, phosphorus for root, seed, and flower development, and potassium is necessary for overall plant health. A cannabis plant requires varying amounts of macronutrients depending on the development stage.
These are almost the same as the macronutrients but are not required in as high quantities as the macronutrients. Secondary nutrients include sulfur, magnesium, and calcium. They are essential in cannabis growth and will need you to maintain proper pH levels for your plant to benefit from them.
Secondary nutrients have crucial functions, including promoting root growth. Sulfur aids in transpiration and metabolism, and transportation of chlorophyll; magnesium makes the chlorophyll that plants use as food; and calcium promotes the absorption and transport of other nutrients. Although the quantities of secondary nutrients are not high, they are still critical in the overall health and growth of cannabis plants.
These refer to minerals and elements that are not easily found on earth and are not needed in high quantities. Their functions include:
This aids in the photosynthesis and production of chlorophyll, together with enzyme interactions.
Iron is necessary for the production of chlorophyll. If your leaves start yellowing, it can be an indication of iron deficiency.
This nutrient helps process nitrogen.
This helps in the development of branches, leaves, and stems. It is also necessary for maturing cannabis plants.
This nutrient helps in strengthening stems and branches. It also assists in the growth of plant protein.
Boron aids in root tips development. Also promotes the absorption of calcium and helps with the transportation of sugars.
They contain a range of different compounds, such as worm castings and bone meal. You can find these being sold individually, or some are mixed with organic potting blends. They give the plant a pleasant aroma and taste and are all-natural, so they do not affect the ecology. They are best used when the plant is grown in the soil because they can clog or promote the growth of unwanted plants when used in a hydroponic system.
These are also called chemical fertilizers, these nutrients show quick results. They help plants grow quickly in a short time and result in higher yields in a short span. They are best used in hydroponic systems and help increase the crop’s potency.
Soil microbes (rhizobacteria)
These nutrients are added to the soil for their ability to produce beneficial byproducts, which increase yields.
Factors to Consider When Buying Nutrients
Some of the other important factors you need to know before buying nutrients for your plants include:
Different brands have different combinations of organic and chemical compounds that they use in their nutrient ratios. These compounds react differently with each other, meaning you can see different nutrient bottles with the same NPK ratios, but they might provide different levels of nutrients. The ingredients used are what determine if the nutrients are organic or synthetic.
There are multiple brands offering nutrients for marijuana plants. Each brand has different ratios that they think are necessary for each growth stage.
Soil or Hydro nutrients
Matching your medium of growing with the nutrients you use is one of the most crucial things. Soil and hydroponic nutrients differ in their nutrients, so you have to be sure that you are getting the correct kind. Hydroponic nutrients usually contain all that your plants need to grow, and you can grow them in any growing medium.
Another thing you need to pay close attention to when dealing with the best nutrients for marijuana is the feeding schedule. The number of nutrients or fertilizers you give to your plants will depend on the growing stage the plant is in and the size. You can create a balanced ratio by adding fertilizer to your water before introducing it to the plant.
Only use nutrients and fertilizers in your plants when they start showing a nutrient deficiency or a few times since you do not want to overwhelm the plant with unnecessary nutrients.
Where you are growing the plants will also determine the feeding schedule to follow. Plants grown indoors do not need as many nutrients because they have a grow light link, while outdoor plants need more nutrients since they grow taller and therefore need high quantities of Nitrogen.
Watering and pH Levels
Other than nutrients, water and pH levels are also essential factors to consider when growing marijuana. Water pH is crucial, especially when using a hydroponic system. If you see your plants displaying deficiency signs even though you give them enough nutrients and fertilizers, it might signify that the pH levels are not satisfactory.
If pH levels are unsatisfactory, the plant has a reduced ability to absorb nutrients which can cause the plant to start withering and show deficiency signs. When growing your plants in a hydroponic environment, the pH levels must range between 5.5 and 6. When growing in soil, the conditions need to be more acidic, so the levels must be between 6 and 7.
Water your plants regularly but take extra care, so you do not overwater them. Too much water can result in little airflow, which in return might make the roots start rotting. Do not be afraid to experiment as much as possible with the water levels to know what the optimal amount for your plant is. Other factors like environment, climate, and the cannabis strain will also help determine the correct quality and quantity of water.
NPK Levels of Cannabis Nutrients in Every Stage of the Cannabis Life Cycle
While on the topic of best marijuana nutrients, we have to consider the NPK levels. This refers to the nutrient ratios that your plant will need for the best results.
The NPK levels refer to the three main macronutrients- Nitrogen (N), Phosphorous (P), and Potassium (K). You will need to use these nutrients throughout the whole cannabis life cycle. There are, however, changes in the quantities needed in each stage, and these include.
Vegetative Growth Phase
The vegetative growth phase refers to the early stages of the plant’s cycle. In this stage, there is a minimal level of nutrient requirements needed. Plants at this stage need a high N feed. Most growers use the 3:1:1 NPK ratio across all the different cannabis strains. At the beginning stage, the nitrogen requirements are higher than those of potassium and phosphorus until the plant reaches the bloom stage.
You will not need to use any nitrogen additives because the soil naturally has enough fertilizers for the beginning of the phase during the first month. At this stage, all you will need to do is to water the plant and be on the lookout for nutrient lockouts.
This is the second stage of the cannabis plant cycle, and it brings about a change in the macronutrient requirements your plants will need. At this stage, you will have to adjust the NPK ratio.
The best NPK ratio recommended is a 1:3:2, which you will use until mid-bloom and then switch to 0:3:3 ratios when the plant gets to late bloom. You will also need to add a flushing solution or use a flush of water to add flavor to the plant.
The amount of P and K will dictate the bud’s size, which is why you must reduce the nitrogen quantities. High nitrogen quantities can spoil the taste and sinsemilla of the bud, giving you a rough stash. It would be best if you used more phosphorus and potassium (P&K) at this stage to increase the chances of getting a better flavor and feel. Avoid using N nutrients in the final ten weeks before harvesting to get the best results.
