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.
Liquid nutrients are typically used for indoor growing, but can be used outdoors too. Liquid nutrients are used for weed plants in soil, hydroponics, and other grow media, and can be pushed through drip lines, misters, and hoses for easy and efficient delivery.
These micronutrients are needed as well, but in much smaller quantities:
Your marijuana plants need the following primary nutrients, collectively known as macronutrients:

One of the best things about organic fertilizers is they improve the soil while also improving the quality of your plants. Other benefits:
Compost tea should never be a 100% replacement for nutrients, but it can be a great complement to other nutrients.
Products are also generally divided into “grow” solutions, high in nitrogen needed for vegetative growth, and “bloom” solutions, high in phosphorus for flower development. You can stick to these general terms if you don’t want to get bogged down with numbers.
A cannabis plant needs many nutrients, and pulls these from the soil. Left on its own, with good soil, plenty of light and water, and a temperate environment, a weed plant will grow fine, but nutrients will help the plant thrive and grow healthy and strong.
When using liquid nutrients for cannabis plants, it’s important to have a watering schedule to write down and track:
Magnesium is one of the most important secondary nutrients. It is rare to experience a magnesium deficiency when you grow weed outdoors. However, it is more common when you grow indoors or if you use a soilless medium. It is a crucial player in chlorophyll production. You must infuse your plant with magnesium immediately if you spot signs of deficiency.
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.
Nitrogen is one of the most common nutrients in cannabis, and growers are aware of its importance. Despite this fact, nitrogen deficiency is common. It plays a significant role in most plant functions, including amino acid production and photosynthesis. Although your plants need nitrogen throughout their life cycle, it is especially important during the vegetative stage.
If a marijuana plant doesn’t receive enough of a nutrient, it will show signs of a deficiency. Let’s explore this issue in greater detail below.
While marijuana plants don’t need a large amount of sulfur, it is still considered an essential macro element. As well as aiding enzyme formation, it helps to construct proteins. Sulfur is also pivotal in the development of chlorophyll molecules. If your plant is deficient in sulfur, calcium, magnesium, or iron, it can display symptoms like yellowing or dying leaves.
Although sulfur deficiencies are uncommon, they can occur if your fertilizer or soil doesn’t already have enough of it. Sulfur is an essential nutrient because it helps plant respiration and the synthesis and breakdown of fatty acids. If your soil or water has an excessively high pH, it could result in phosphorus loss. This is a major cause of sulfur deficiency.
There are 17 essential mineral elements for plant growth broken up into macro and microelements or nutrients.
Immobile nutrients stay in the same place once the plant assimilates them. You will spot signs of immobile nutrient deficiency in young leaves near the plant’s top and outer branches.
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.
Nitrogen is by far one of the most essential nutrients of the cannabis plant. It is so crucial because it is an integral part of chlorophyl and is key in the process of photosynthesis. Plant tissue is also made up of mostly nitrogen, which is why you will quickly see signs of deficiency when there is an absence of it. For a plant to feed itself and grow, there must be a readily available source of nitrogen within the soil or grow medium. Some of the most popular organic elements that are used for nitrogen supplementation include alfalfa meal, blood and bone meal, cottonseed meal, chicken manure, feather meal, fish meal, bat guano, worm castings, and many other natural resources.
Potassium, the 3rd macronutrient, next to Nitrogen and Phosphorus, is another important catalyst in the cannabis plant. Although the presence of potassium is very limited in the plant tissue, it interacts with nitrogen and participates in the compound of proteins and amino acids. During periods of drought, it improves the resistance of plants and is the main component to the strength of plant tissues. Potassium also works in conjunction with phosphorus to improve the strength and resistance of the root structure. It also plays a major role in the increase of mass, density, and volume of the buds. The most used potassium organic material include compost, kelp meal, greensand, sulfate of potash, and wood ashes.
