Cannabis, like all living things, needs essential nutrients to live, grow, and flourish. These essential nutrients are divided into two groups: macro and micro-nutrients. Macro-nutrients are essential for growth and development, while micro-nutrients are important for overall health and wellbeing. These essential nutrients play a crucial role in the cannabis plants’ growth, health, and well-being and the optimal growth and production of quality buds.
Macro-nutrients are the first and most important group of essential nutrients that cannabis plants need. These nutrients include nitrogen (N), phosphorus (P), and potassium (K).
Nitrogen (N) helps cannabis plants grow strong stems, lush foliage, and promotes the production of chlorophyll, which is essential for photosynthesis. Without enough nitrogen, cannabis plants will have weakened stems and slow or stunted growth. Too much nitrogen can be just as damaging, causing a nutrient burn and can lead to deficiencies in other elements.
Phosphorus (P) helps cannabis plants build strong root systems, induce flowering, and increases their size and potency of buds. Without enough phosphorus, the plant will be weak and stunted, and buds will be potentially small and less potent. Too much phosphorous can be damaging as it can cause a nutrient burn.
Potassium (K) helps cannabis plants’ support general growth and development and helps the plant uptake other essential nutrients through its cell walls. Without enough potassium, the plant will be slow to grow and buds will be sub-par. Too much potassium can be just as damaging as it can cause a nutrient burn and can reduce the absorption of other necessary macro-nutrients.
Micro-nutrients are the second group of essential nutrients, and while they are not required in large amounts, they are still essential for a successful cannabis grow. The most important micro-nutrients are calcium (Ca), iron (Fe), magnesium (Mg), sulfur (S), manganese (Mn), zinc (Zn), boron (B), copper (Cu), and molybdenum (Mo).
Calcium (Ca) helps to strengthen the cell walls and prevents nutrient deficiencies. Too much or too little calcium can reduce the plants’ growth, stunt buds and even cause nutrient deficiencies.
Iron (Fe) is an essential trace nutrient for cannabis plants and helps the plant uptake and use other essential nutrients, and without it, it can cause chlorosis (yellowing of leaves) and weak, unhealthy plant growth.
Magnesium (Mg) helps the plant produce chlorophyll, which is essential for photosynthesis, and without it, the plant will yellow and slow in growth. Too much magnesium can cause a nutrient burn, but it’s more common for cannabis plants to suffer from a magnesium deficiency.
Sulfur (S) helps the plant uptake other essential nutrients and works in concert with other macro and micro-nutrients. If a sulfur deficiency occurs, the plants will grow slowly and weak.
Manganese (Mn) helps the plant uptake and utilize other essential nutrients. A lack of manganese can cause yellowing and stunted growth, however too much can be just as damaging as it can cause a nutrient burn.
Zinc (Zn) helps the plant uptake and use other essential nutrients and can help prevent deficiencies. Too much zinc can be damaging, and a zinc deficiency will cause slow, stunted growth and yellowing.
Boron (B) is involved in the translocation of other essential nutrients, and without it, the plant will suffer from nutrient deficiencies. Too much boron can cause nutrient deficiency and a nutrient burn, so it’s important to make sure it remains in balance.
Copper (Cu) helps the plant use several essential nutrients, and without it, plants will suffer from growth stunting and weak foliage. Too much copper can be damaging, as it can cause a nutrient burn
Molybdenum (Mo) is essential for the use of some essential macro-nutrients, and without it, the plant can suffer from a deficiency in nitrogen and phosphorus. Too much molybdenum can be damaging as it can cause a nutrient burn.
These essential nutrients, both macro and micro-nutrients, are absolutely essential to a successful cannabis grow. Without them, the cannabis plants won’t be able to produce the high-quality buds and plants that we desire. As with all things, it’s important to pay attention to the balance of nutrients and not overboard with any one element in order to ensure the best possible growth and yield from your cannabis plants.
