Cannabis plants are hardy and can withstand a wide range of growing conditions, but to achieve the best results, it’s important to give them the nutrients they need.

The type of cannabis you’re growing, the stage of growth, the size of your plant, and the conditions in your grow room will all play a role in determining how much and what kind of food your plant needs.

In general, cannabis plants need three things: water, light, and nutrients. Of these three, nutrients are often the most difficult to get right. Too much or too little of even one type of nutrient can lead to problems that can be difficult to fix.

This guide will teach you the basics of cannabis nutrition and how to create a nutrient solution that is tailored to your plants’ specific needs.

The Basics of Feeding Your Cannabis Plant

In order to ensure a healthy and bountiful harvest, your cannabis plant needs the right nutrients. Just like any other plants, cannabis plants need nitrogen, phosphorus, and potassium to grow. However, cannabis plants also need other minerals like calcium and magnesium. This article will cover the basics of feeding your cannabis plant so that it can grow strong and produce lots of buds.


Your cannabis plant needs three primary macronutrients for healthy growth: nitrogen (N), phosphorus (P), and potassium (K). These are typically represented by the N-P-K value listed on fertilizer products. Cannabis also needs secondary macronutrients, such as calcium, magnesium, and sulfur, but in smaller amounts.

Nitrogen is responsible for foliage growth, so it’s important for the vegetative stage of growth. Too much nitrogen during the flowering stage can result in fewer flowers or buds. Phosphorus is key for root development and aids in theflowering process. Potassium helps plants withstand stress, promotes root health, and aids in water absorption and nutrient transportation.

Cannabis plants need different ratios of nitrogen, phosphorus, and potassium at different stages of their life cycle. In general, a ratio of 2-1-1 or 3-1-2 is suitable for most plants during the vegetative stage. For flowering plants, a ratio of 1-1-1 or 1-2-2 is often recommended.

It’s important to note that Cannabis plants absorb nutrients differently depending on the stage of growth they are in. Seedlings and clones have different nutrient needs than vegetative plants, which have different nutrient needs than flowering plants. Make sure you are using a fertilizer that is appropriate for the stage of growth your plant is in.


While macronutrients are needed in large amounts to support basic plant growth and development, micronutrients are only needed in very small, or trace, amounts. However, micronutrients play extremely important roles in plant growth and health. Just like humans need vitamins and minerals to function properly, so do plants!

There are many different micronutrients that are essential for plant growth, but some of the most important include iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu). Micronutrient deficiencies can lead to a number of problems for your cannabis plants, including stunted growth, yellowing leaves, and leaf tip burn.

Fortunately, most soil mixes already contain sufficient levels of micronutrients for healthy plant growth. However, if your plants are not getting enough micronutrients from the soil, you can supplement with a quality liquid fertilizer or compost tea. You can also add organic matter to your soil to help improve nutrient availability.


Cannabis plants are sensitive to the pH of their root zone. The ideal range for cannabis is between 6 and 7, with 6.5 being ideal. Most soil and soilless mixes already have the perfect pH for cannabis, but if your water is very alkaline or acidic, it can affect the pH of your root zone over time. To maintain a stable pH, you will need to periodically check and adjust your water and/or media.

If the pH of your root zone gets too high or low, it can “lock out” essential nutrients that your plant needs to survive and thrive. For example, if the pH of your water is too low (acidic), it can cause a nutrient deficiency even if there are plenty of nutrients in your soil or soilless mix. This is because the roots are not able to absorb them properly. Conversely, if the pH of your water is too high (alkaline), it can make nutrients toxic to your plant even if there are few nutrients in your soil or soilless mix.

There are several ways to adjust the pH of your water, but the most common method is to use a product called “pH Up” or “pH Down”. These products are sold at most garden stores and online retailers. You will also need a way to test the pH of your water, which can be done with test strips or a digital meter.

To adjust the pH of your water, simply add a small amount of “pH Up” or “pH Down” until it reaches the desired level. Be sure to test the pH often during this process so that you do not overshoot the target level. Once you have reached the desired level, you can then proceed with watering your plants as usual.

The Best Foods for Your Cannabis Plant

If you want your cannabis plant to grow big and strong, you need to feed it the right food. Just like any other plant, cannabis plants need nutrients to survive. However, cannabis plants are a bit different from other plants in that they need different types of nutrients. In this article, we will discuss the best foods for your cannabis plant.


Fertilizers are an important part of cannabis cultivation. They provide the nutrients that plants need to grow and produce healthy flowers. There are many different types of fertilizers on the market, and it can be difficult to know which one is best for your plant. Here is a quick guide to some of the most popular fertilizers for cannabis plants:

-Compost: Compost is a great all-purpose fertilizer for cannabis plants. It’s made from decomposed organic matter, and it’s full of nutrients that plants need.
-Fish emulsion: Fish emulsion is a popular fertilizer for cannabis plants. It’s made from fish remains, and it’s full of nutrients that plants need.
-Cocoa shells: Cocoa shells are a great source of nitrogen for cannabis plants. They’re also high in potassium, which is essential for plant growth.
-Bone meal: Bone meal is a great source of phosphorus for cannabis plants. It’s also high in calcium, which is essential for plant health.


Compost is a nutrient-rich organic matter that can be added to cannabis plants in order to improve the quality of the soil. It is made up of decomposed leaves, twigs, and other plant matter. Cannabis plants thrive in soils that are high in organic matter, so compost can be a great way to give them the nutrients they need.

There are a few different ways to get compost for your cannabis plant. One way is to purchase it from a gardening store or online. Another way is to make it yourself at home. If you choose to make your own compost, you will need to find a location that is away from any potential sources of contamination, such as pet waste or food scraps. You will also need to ensure that the compost pile has access to air and water so that it can break down properly.

Once you haveprocured or made your compost, it is time to add it to your cannabis plant’s soil. The amount you add will depend on the size of your plant and the type of soil you are using. In general, you should add about 2 inches (5 cm) of compost per square foot (0.09 m) of soil. Be sure to mix it in well so that the roots of your plant can access the nutrients easily.


Manure is a great source of nutrients for your cannabis plant. It is high in nitrogen, phosphorus, and potassium, which are essential for plant growth. Manure also contains other essential nutrients that your plant needs. Manure is a great way to add organic matter to your soil, which will improve the soil structure and drainage.

How to Feed Your Cannabis Plant

Cannabis plants are like any other plant in that they need the right nutrients to grow healthy and strong. There are a few things to keep in mind when feeding your cannabis plant. First, you need to know what kind of nutrients your plant needs. Second, you need to know when to feed your plant. And third, you need to know how much to feed your plant.

Fertilizing Your Cannabis Plant

Fertilizing your cannabis plant is an important part of growing healthy and vibrant plants. There are many different ways to fertilize your plants, and the best method for you will depend on the type of soil you are using, the type of plants you are growing, and your personal preferences.

If you are using a soil mix, you will probably need to supplement with additional nutrients, either through a liquid fertilizer or by top dressing your plants with a dry fertilizer. If you are growing in hydroponic systems or coco coir, you will need to use a nutrient solution specifically designed for hydroponics or coco.

When choosing a fertilizer, it is important to select one that is high in nitrogen for vegetative growth and high in phosphorus for flowering and fruiting. You can also find fertilizers that are formulated for specific stages of growth, such as vegetative or flowering/fruiting.

Once you have selected a fertilizer, it is important to follow the manufacturer’s directions carefully. Over-fertilizing can damage your plants, so it is better to err on the side of under-fertilizing than over-fertilizing. If you are unsure about how much fertilizer to use, start with half the recommended amount and work up from there.

Watering Your Cannabis Plant

Cannabis plants need to be watered regularly, but not too frequently. The frequency of watering will depend on several factors, such as the size of the plant, the type of soil, the temperature, and the humidity. If you are growing in soil, you will usually need to water your plants every 1-2 days. If you are growing in hydro ( hydroponics ), you will need to water your plants more frequently, usually every 12 hours.

To water your cannabis plant, simply remove it from its pot and place it in a sink or tub filled with room-temperature water. Allow the plant to soak for 5-10 minutes, then remove it from the water and allow it to drain for a few minutes before replanting it.

It is important not to over-water your cannabis plant. Over-watering can lead to problems such as root rot and leaf drop. If you think your plant may be overwatered, simply stop watering it for a day or two and see if the problem improves.

When to Feed Your Cannabis Plant

Cannabis plants need to be fed depending on their stage of growth. The general rule is to give them more food as they get bigger and less food as they get smaller.

For example, a young cannabis plant in its vegetative stage will need to be fed more often than an adult cannabis plant in its flowering stage.

Here is a general guide for when to feed your cannabis plant:

-Seedlings (up to 2 months old): Once a week
-Vegetative stage (2-8 months old): 2-3 times a week
-Flowering stage (8-12 weeks): Once a week or every other week
-Harvested plants: No need to feed


Now that you know the basics of cannabis nutrition, you can make informed decisions about what kind of food to give your plants. Remember, every strain is different, so what works for one may not work for another. The best way to figure out what your plants need is to experiment and keep track of the results. With a little trial and error, you’ll be able to create a nutrient regimen that keeps your plants healthy and productive.
