Cannabis macronutrients are valuable materials in your cannabis nutrient blend, like iron, zinc, magnesium, calcium, etc.
What are secondary nutrients?
Essential secondary nutrients include calcium (Ca), sulfur (S), and magnesium (Mg). These nutrients are often unavailable to cannabis without proper pH level maintenance. Therefore, secondary essential best cannabis nutrients are critical to adequate cannabis plant development.
Here’s how to know when your cannabis plants need secondary nutrients:
- Calcium: growth is stunted, leaves have dead spots with dark green around them
- Magnesium: veins and outer edges take on a light green or yellow-ish hue
- Sulfur: leaves begin to yellow at the midsection before becoming completely yellow
What are cannabis micronutrients?
Cannabis plants need them in smaller quantities, but micronutrients play an essential role in their physiology. Micronutrient deficiency is somewhat rare, but without them, it’s challenging to realize healthy yields and potent plants.
Here’s how to know when your plants need cannabis micronutrients:
- Boron: spotting on new leaves and abnormal or thick growth at tips
- Chlorine: leaves yellowing, wilting, and stubby roots
- Copper: leaves are shiny or have dark blue or purple undertones
- Iron: new shoots and leaves appear yellow
- Manganese: yellow leaves quickly turning brown
- Molybdenum: leaves turn orange, red, or pink around the edges
- Zinc: fresh leaves don’t open up; buds are loose and fragile
Cannabis Grow Types and Nutrients
What cannabis nutrients do hydroponic grows use?
Regardless of the cultivation method, cannabis plants need several essential nutrients to thrive. In hydroponic cultivation, those include:
- Trace Micronutrients and Elements
- Amino Acids and Vitamins
How do you measure nutrients in the soil?
- PPM, or parts per million, can be measured using a TDS (total dissolved solids) meter.
- EC or electrical conductivity can be measured using an EC reader.
Why flush your cannabis plants?
The last step before harvest, flushing, allows plants to absorb any nutrients left in the soil by removing nutrient buildup at the roots.

What cannabis nutrients are used for outdoor grows?
While it varies based on your soil, here are the best nutrients for outdoor grows:
Cannabis Nutrients for Grow and Feed Stages
What are the best nutrients for cannabis seedlings?
Here are the best nutrients for cannabis seedlings:
What are the best nutrients for vegging cannabis plants?
The cannabis vegetative stage lasts between four and twelve weeks. Cannabis plants require significant light and nutrients during this period.
The best nutrients for the veg stage are the same essential nutrients for any cannabis plant. Still, their NPK ratio will vary as follows:
- High nitrogen
- Moderate potassium
- Low phosphorus
What is nutrient burn?
Cannabis nutrient burn describes the stress plants are exposed to when they’ve been given more nutrients than needed in a given growth phase.
What is nutrient lockout?
When plants have the incorrect pH balance, water chemistry, light level, temperature, or nutrients, they won’t properly absorb nutrients.
What is nutrient overfeeding?
Overfeeding marijuana nutrients occurs when the roots absorb excess nutrients, preventing water from being transferred through the rest of the plant.
What is nutrient deficiency?
Cannabis nutrient deficiency occurs when plants don’t have the essential nutrients required for optimal growth.
