General hydroponics CALiMAGic quart secondary nutrient

If you’re new to marijuana cultivation or you’re dealing with nutrient deficiencies, or probably, your marijuana is getting destroyed from overfertilization. Realizing the best nutrients for your marijuana species can be quite tasking, time-consuming, and confusing, especially if you’re a first-time marijuana grower.

There are several nutrient-making companies on the market, and each develops various kinds of nutrients for various purposes. However, there are two significant stages of life for a marijuana plant, and these are the; flowering stage and the vegetative growth. Now, each of these stages requires certain nutrients to be successfully completed.

NPK, which stands for Nitrogen, Phosphorus, and Potassium, is a complex fertilizer that comprises majorly of the three primary nutrients that are needed for healthy and complete plant growth. NPK is the essential nutrients that marijuana plants need to grow strong and healthy.

Some plant’s nutrients requirements differ from others. Applying these or any chemicals haphazardly may do more harm than good sometimes. When used on some plants, a fertilizer that has a high level of nitrogen can make them to use up all their energy and strength into developing foliage rather than flowers. However, nitrogen is an essential element for growing marijuana plants. If you have purchased chemicals for the care and cultivation of marijuana plants, you will notice a small inscription uniquely placed on the fertilizers’ bags or cans. Inexperienced growers may miss this detail. What these chemicals have inscribed on them are the initials written as ‘NPK’ – meaning there is a presence of Nitrogen, Phosphorus, and Potassium in the fertilizer. Sometimes the letter ‘S’ is added to represent sulfur.

Now that you know these initials and what they stand for, you need to know that marijuana plants need nitrogen, Phosphorus, and Potassium all through their life cycle and stages of growth. Each of these nutrients above plays a unique and equally important role in the development of your marijuana plants and, as such, shouldn’t be ignored. Here are the vital roles that each of these nutrients offers to your cannabis plants :

  • Nitrogen

Even though nitrogen is continuously present in the atmosphere, most of these plants cannot absorb it straight from the air. These plants can only soak it up from the soil using their roots. It is essential and required for photosynthesis and plays a vital role in your plant’s diet, especially during its vegetative stage of growth.

  • Phosphorus

Phosphorus is not as easy as nitrogen to find in its natural form or the environment. This is most likely because it is incredibly reactive to other chemical or non-chemical substances. However, Phosphorus is essential for developing strong roots. Most marijuana plants, when flowering, require added Phosphorus, which is signified in the high concentration of Phosphorus in most fertilizers designed for the flowering stage.

  • Potassium

Like nitrogen and Phosphorus, Potassium helps strengthen the plant’s metabolism and is also essential for photosynthesis and the production of key proteins in the plant. It is also required to strengthen the immune system of your plant and builds its resistance against pests, infections, and diseases.

A basic guide to NPK ratios for Cannabis

Just as we’ve discussed earlier, NPK nutrients may not be used in the same ratio throughout the life cycle of the cannabis plant. Also, marijuana plants have significantly different requirements based on the strain.

  • Vegetative growth

In the early stages of the marijuana life-cycle, the required nutrients are small. Therefore, less is more in the early stages of growth in a cannabis plant. Many growers prefer a feed with a high content of nitrogen. Using an NPK ratio of N:3, P:1, K:1, you can ensure an excellent supply of macronutrients during the growing stage of almost all kinds of Cannabis. However, there are some strains that may not respond well to this particular ratio, so you may have to adjust the ratios a bit based on the needs of that particular strain.

You have to ensure that the Nitrogen levels are particularly higher than Potassium and Phosphorus until the bloom phase.

  • Flowering

Once the marijuana fully transitions to the flowering stage, Its requirement for macronutrients changes to the direct opposite. This means that you would have to re-adjust the NPK ratio. The practical and recommended NPK formula for the flowering phase during early to mid-bloom is 1:3:2, closely followed by 0:3:3 for late bloom. Best light for flowering

  • Feeding: light, heavy and perfect

Soil growing only requires watering of the plants, especially at the seedling stage. Also, adding some extra microorganisms and enzymes that are beneficial to the plant is enough. This will make the nutrients in the soil available for the plants whenever they need it and also helps to develop the roots of your plant. Although, for hydro and coco growers, it is advised that you begin an application with strength feeds of 25% and then adjust it as you go. Some strains like the indica strain may react better to high doses of nutrients or fertilizer. On the other hand, sativa responds better to lesser nutrients. Most auto-flowering and hybrid strains respond well to just enough fertilizer, not too high and not too low doses will do just fine.

Calcium and Magnesium also play vital roles in the development of your plants. A soil that is rich in all nutrients but lacks calcium is likely to grow plants that are noticeably deficient. Calcium strengthens the plants and helps the plants absorb and make use of the available nutrients quickly. Calcium also helps to paralyze toxic materials and can improve the texture of your soil.

Magnesium is also an essential micronutrient that helps the plants maximize the available nutrients and use them. Also, the plant enzymes require Magnesium to produce sugars and carbohydrates. To achieve healthy flowers, fruits, and seeds, your plants need a sufficient amount of Magnesium. Also, Magnesium plays a vital role in the process of photosynthesis, and the plants cannot process the sunlight without it.
