Marijuana, just like any other plant, requires nutrients to properly grow and flourish. The three most important nutrients that marijuana requires are Nitrogen, Phosphors, and Potassium. These 3 combined are also known as macronutrients for cannabis growth. However, the amount of each of these nutrients depends upon the growth phase of the plant. The guide below will offer an informative insight on when and how to fertilize marijuana crops to maximize the yield.
Marijuana As A Seedling
The seed wouldn’t require anything more than moisture and humidity when you sow it in the ground. However, once the seed will germinate and roots will start expanding, the little marijuana crops will initially require nitrogen. Nitrogen, other than being a growth stimulant, helps is cell enlargement. Which is why it’s needed in higher doses during the growth stage. Keep increasing the amount little by little as the plant continues to grow.
Whilst marijuana will require nitrogen throughout its life, the requirement for potassium and phosphorus will significantly increase once the plant starts flowering. Leaves and stems of marijuana crops use nutrients to spike up photosynthesis since the buds require more food to grow to their full capacity. Also, phosphorus helps in keeping certain pests at bay. It protects the leaves and buds.
Other than these 3 nutrients, marijuana crops also need minerals like magnesium, iodine, and calcium. You can prepare your own organic soil fertilizers with the help of the following organic ingredients.
Ingredients To Supply Nitrogen:
- Worm castings
- Bat guano
- Chicken manure
Ingredients To Supply Phosphorus:
- Banana peels
- Bone and fish meals
Ingredients to Supply Potassium:
- Rock dust
- Wood ash
Ingredients To Supply Magnesium:
- Epsom salt
Some Important Fertilization Tips
The following fertilization tips will feed your hungry cannabis plants to perfection without damaging the roots.
- Add fertilizers in the water when the plant is small.
- If the leaves take extremely dark green color, it means you’re overfeeding nutrients. Cut out on the supply of phosphorus and nitrogen.
- If the leaves become yellowish and plan, the plant isn’t getting enough phosphorus and potassium. Increase their supply.
- Cannabis requires less nitrogen during the flowering stage because more nitrogen will most likely keep the plant in the vegetative state only. As a result, the buds will become weaker.
- The vegetation stage should have a patch of water scarcity. It will increase the yield because plants will tend to absorb more nutrients from the soil to make up for the lack of water.
