There are many different cannabis nutrients out there and it may be overwhelming knowing where to start. Here’s a breakdown on some of our favorites.
Organic fertilizers are nutrients that come from organic sources such as animal and vegetable waste. They also include sediments like glacial rock dust and gypsum that contain beneficial minerals for the soil and plant. They are common for outdoor growing and usually come in powder form.
Using organics is also great if you want to be more in-tune with your natural environment. Organic fertilizers are readily available from renewable sources and are an earth friendly option.

The tea can be applied to roots or as a spray on leaves of your cannabis plants. Dilute the tea with water at a ratio around 1:20 when applying it to roots. A basic tea can’t harm or burn your plants, so you can apply a potent dose freely. As a foliar spray, compost tea is generally diluted with water at a 1:2 ratio.
Nitrogen is also part of amino acids that act as building blocks for proteins in a plant. Without the necessary proteins, your cannabis plants will be weak and frail. Nitrogen is also a part of ATP, which allows plant cells to control the use of energy.
Comparing nutrient and fertilizer brands
Additionally, cannabis plants derive these non-mineral elements from air and water:
Nutrient solution bottles and fertilizer bags will indicate how much of the three main nutrients are in the product, in the form of N-P-K: Nitrogen, phosphorus, and potassium, For example, a product that says “10-4-4” will contain 10% available nitrogen, 4% phosphorus, and 4% potassium by weight.

It is fairly unusual for marijuana plants to exhibit a phosphorus deficiency. One of the main reasons involves the pH of the water or growing medium going above 7.0. Your plants need phosphorus for photosynthesis. Phosphorus also helps the release of stored energy in carbohydrates.
Calcium and magnesium are often overlooked when discussing the growth of the cannabis plant. It is common to find them together in a single Cal-Mag supplement, which generally contains iron as well. These nutrients are essential to the process of photosynthesis, which involves creating energy from light. Magnesium is particularly crucial for photosynthesis; it is the central atom in the chlorophyll molecule.
You can correct a deficiency by purchasing fertilizer with the right NPK ratio. Quick treatments include urine and bat guano. If you spot a nitrogen deficiency, act fast because your plant’s yield will be significantly affected otherwise.
The first three nutrients listed above – Nitrogen (N), Phosphorus (P), and Potassium (K) – are the most crucial. If you purchase a bag of nutrients from a store, you should notice an N-P-K ratio listed on it.
It is best to reduce the proportion of nitrogen to phosphorus and potassium during flowering compared to the ratio used during the vegetative stage. It is essential to lower the portion of N at this point. It can reduce bud development and promote vegetative growth instead of generative (also known as flowering) growth.
Maintaining higher proportions of P and K is critical when flowering. This is because the plants use larger amounts during the flowering stage than during the vegetative stage.
Certain types of water don’t include large amounts of calcium; this makes them a poor choice if using a hydroponic system. You can treat a deficiency by using a calcium-rich substance such as lime.
Botanicare is a great company that’s been around for as long as I’ve been growing, and whose supplements I’ve been using for years (specifically, their Hydroguard supplement is the most effective thing I’ve used to prevent root rot in a hydroponic setup). Best for…
