Cannabis growing deficiencies

“Cannabis requires three primary, or macro-nutrients, for optimal health. These are Nitrogen (N), Phosphorous (P), and Potassium (K), or N-P-K.”

“The pH-levels of your nutrient-water solution play an important role in keeping your cannabis plant healthy.”

Calcium – Calcium deficiencies can be hard to diagnose. On the leaves, look for dead spots, crinkling, small brown spots, stunted growth, small or distorted leaves, curled tips, and dark green around the affected spots. Calcium, magnesium and iron deficiencies often appear together. The best way to restore is to flush your plants with clean pH neutral water, and then resupply the water nutrient solution. You can also supplement your nutrient-water solution with Cal-Mag to avoid calcium and magnesium deficiencies in the future.

All immobile elements aim to provide the cannabis plant with a balanced amount of vitamins and needful hormones. Additionally, they regulate the content of prolific phytocannabinoids (THC and CBD). So, it is necessary to pay attention to “Sulph”, “Cal”, “Mag” deficiency symptoms and character of their excess.

Many cultivators face cannabis leaf problems caused by deficiencies and excesses of nutrients. Both lack and excessive surplus of nutritive matters are harmful for the cannabis plants. Your harvest can be in danger if there is an imbalance of key factors and nutrients takes place. It is necessary to pay attention to all types of nutritional agents that provide healthy growth of your plants.

The last stage is the most dangerous for your plants. After yellow spots on the marijuana plant are noticed, the potassium-rich solution should be used immediately. Cannabis leaves curling down is a sign of almost snag herb.

This group is notable with three main mobile elements: Nitrogen (N), Phosphorus (P), Potassium (K). Speaking about Nitrogen, it is worth mentioning that this element provides healthy formation of leaves. If cannabis leaves are turning yellow, the Nitrogen deficiency takes place. Water your plants with the nitrogen-rich solution to recompense a lack of N-element.

Macronutrient excess and deficiency in cannabis plants

Let’s research into marijuana plant deficiencies and nutrient overbalance. Macronutrients are considered the most important ones for the healthy leaves, generous harvest and mass cannabis production.

Phosphorus excess is seldom noticed. Nevertheless, do not use off-the-scale amounts of these nutritional agents. The last macronutrient from our list is Potassium. This nutrient is responsible for the flower formation process. One of the most dangerous nutrient plant deficiencies cannabis afflicts with is lack of Potassium. All leaves become brown, unhealthy yellowing takes place. Take a look at the cannabis deficiency chart to notice changes that Potassium liability brings.

There are three kinds of nutrients that treat problems with cannabis leaves:

An appropriate cannabis growing – types of nutrients

Pay attention to PH content to help marihuana leaves become salutary ones. Nitrogen excess is notable with cannabis leaves curling up. Their color can stay green but the shriveled surface of vegetation is indicative of leaves in poor condition. It is recommended to allow soil drying, then enzyme solution should be used for watering.

Phosphorus is responsible for the root system. It provides nutrients to root boosters. If you see that new greenery becomes weak and decreases in size by several times, the Phosphorous leaf deficiencies take place. The best way to treat sick plants is to mix a phosphorus-rich solution with appropriate PH content. Note that zinc and iron overbalance in damping water can cause P-nonavailability.
