Just like humans need vital nutrients to survive, so do cannabis plants. There are several kinds of important nutrients that the cannabis plant needs, including macronutrients and micronutrients. The pH-levels of your water solution play an important role in keeping your cannabis plant healthy. There are some significant signs that the cannabis plant is deficient in nutrients such as boron, copper, calcium, iron, magnesium, nitrogen, and zinc. If these things are happening to you, don’t fret, we have the answers!
Cannabis requires three primary, or macro-nutrients, for optimal health. These are Nitrogen (N), Phosphorous (P), and Potassium (K), or N-P-K. All plant-food labels include the percentage of these three elements in numerical form, and are presented as N-P-K levels.
Micronutrients are equally important, but only very tiny amounts are required and many, if not all, are readily available in potting soils without the need to add extra. If you are growing hydroponically, then these trace elements are found in most N-P-K solutions–isn’t that handy! These micronutrients, or trace-elements are: Calcium (Ca), Magnesium (Mg), Sulfur (S), Manganese (Mn), Boron (B), Zinc (Zn), Iron (Fe), Molybdenum (Mo), Chlorine (CL) and Copper (Cu).
Nutrient deficiencies can be avoided by being attentive and careful with the pH level of your nutrient-water solution. The reason your plant is deficient of these nutrients is because they are not getting absorbed. Incorrect levels will lock out certain nutrients thus giving you adverse effects. If you are consistent in feeding your plants their nutrients, it’s probably that the pH is either too high or low and the plant is not absorbing them.
