Nutrients For Weed In Veg Stage

There are a number of nutrients for weed in veg stage. Here is a list of the most important ones:


Nitrogen is a key nutrient for growing cannabis, used to make proteins and amino acids. These are what give your plant its growth strength and resilience. Nitrogen also helps create chlorophyll in the leaves so that they can capture energy from the sun (photosynthesis).

In veg stage, nitrogen helps your plants grow their roots deeper into the soil where they will find water and nutrients more easily. As an added benefit, if you feed your plants too much nitrogen they will produce more buds!


Phosphorus is a macronutrient that plays an essential role in plant growth and development. It’s also involved in photosynthesis, respiration, root growth, fruit development and flower formation.

In plants it helps to produce sugars through photosynthesis which are then used during reproduction and the production of seeds.

Phosphorus deficiencies lead to stunted plants with dark green leaves with purplish veins due to lack of chlorophyll production. Leaves may appear cupped or curled inward at the edges which can eventually cause them to wither away completely if left untreated long enough—this can also occur if there’s too much water or humidity around your plants (more on this later).

If you’re having trouble finding signs of nutrient deficiency because your plant is healthy overall but still seems like it could use a little something extra: try adding some chicken manure tea!


Potassium is a very important nutrient for your plants. It helps your plants build strong roots, healthy stems and leaves and grow big and strong. Potassium can also help your plant grow fast!

Calcium is a crucial nutrient for plants in the veg stage.

  • Calcium is used to boost growth, strengthen cell walls and leaves, and strengthen roots.
  • Calcium helps with oxygen absorption, which encourages healthy plant growth.

As you probably know by now, calcium can be found in dairy products like milk or cheese (but not butter—don’t add it to your soil!).


Magnesium is a secondary nutrient that helps with photosynthesis, chlorophyll formation and cell wall development. It’s also important in the absorption of other nutrients.

Magnesium helps to produce seedlings that are healthy and strong. Plants need a lot of magnesium when they are young so it’s best to feed them during this stage to ensure they grow as fast as possible with maximum yield potential.

Because Mg is a secondary nutrient, you don’t have to worry about overdoing it compared to N-P-K which can easily be overdone if you aren’t careful or don’t know what you’re doing!

As a grower, it is your responsibility to ensure that your plants have all the nutrients they need to thrive. If you don’t provide them with what they need, they’ll either suffer from deficiencies or fall victim to pests and disease. In this short article, I’ll tell you everything you need to know about fertilizing in veg stage.

  • Nitrogen: Nitrogen is essential for photosynthesis (the process by which plants convert light into energy). It also aids in growth and flowering. When growing weed indoors under artificial lights, nitrogen should be provided at least once per week until vegetation has been established (about 3 weeks). After that point, fertigation should continue every 2-3 days until you move into flower stage and switch over to an all-organic setup.* Phosphorus: Phosphorus promotes root growth as well as flowering while also contributing towards healthy chlorophyll production.* Potassium: Potassium helps regulate plant functions relating directly or indirectly with reproduction processes.* Calcium: Calcium plays an important role in cell wall structure development along with aiding in overall health—especially when dealing with strains that tend towards having weak stems.* Magnesium: Magnesium helps regulate various metabolic reactions within each cell unit of cannabis plants such as photosynthesis

It is important to note that all plants require other vital macronutrients like sulfur and iron, as well as micronutrients like boron and manganese. However, these are generally present in sufficient quantities within the soil or nutrients solution and do not need to be added in large quantities unless your grow space has a deficiency. On that note, we hope this list has been helpful for understanding what you should be feeding your cannabis plants during their vegetative stage of growth.
