Primary and Secondary Nutrients Needed for How to Grow Weed Indoor Plants

Feeding your weed plants with more nutrients does not mean they can grow faster and produce a bigger yield. Provide them with the proper and just the right amount of nutrients they need because too much fertilizers/nutrients may also burn the top of your plants. Foliar feeding is also a good way of introducing nutrients to your plants to avoid salt buildup in the soil. This can be done by dissolving the fertilizer in water and you can already spray the nutrient mix solution on the foliage. With foliar feeding, the leaves are allowed to absorb the nutrients directly into their veins.

Nutrients/fertilizers are necessary for the different stages of marijuana’s growth. If you desire for fast-growing cannabis plants that can give you a bigger harvest of good quality buds, it is essential that you know what to feed your marijuana plants, when to feed them and how much amount you can give.

When to Provide the Marijuana Plants with Nutrients?

Nutrient feeding is not yet necessary when marijuana is still on the seedling stage. But as soon as they start vegging, weed plants will call for different types and amount of nutrients to support their growth. How much the plants need will depend on which level of growth they are in.

Vegetative stageduring this stage, the cannabis plants need a high amount of nitrogen and low level of phosphorus. These substances will help in the proper development and growth of the leaves and stem for healthy marijuana plants.

Flowering stageduring this stage of growth, the marijuana plants will require low nitrogen but a high amount of phosphorus. In the blooming stage, feed the plants with the basic NPK in the ratio of 5-25-9 to help increase the size of the buds.

Primary Nutrients for Weed Growth

Nitrogen, phosphorus, and potassium are the three primary nutrients needed by weed plants from vegging up to the flowering time. Nitrogen is responsible for the proper growth of the stems and leaves, as well as the overall growth of the cannabis plants during vegging. Potassium helps in promoting stronger root system and ensures good water uptake as it helps the plants resist common diseases. For quality and big buds, marijuana plants need the right level of phosphorus during the flowering phase.

Secondary Nutrients for Cannabis Growing

Secondary nutrients such as sulfur, magnesium, and calcium are also necessary but when you are growing marijuana in soil, these micronutrients may not be added because most soils already contain these elements from decomposing organic substances.

The secondary nutrients are usually given to the plants grown in a hydroponic system. Sulfur aids in the absorption of other nutrients and used in the production of hormones and vitamins that the marijuana plants need all throughout the different stages of growth. Calcium is necessary for cell growth and maintenance of healthy roots while magnesium is an important element so weed plants can properly absorb much light needed. Aside from the three mentioned secondary nutrients, the most common micro-nutrients necessary in your indoor pot grow are manganese, zinc, and iron.
