Which Nutrient Additives Are Right for Your Cannabis?

When you’re growing cannabis plants, the soil is the life force under every root. It consists of healthy organic matter, including animal manure and beneficial microbes and fungi, to help your cannabis thrive. Which nutrient additives are right for your cannabis?

When Should I Provide Additives?

You can begin providing your cannabis plants with nutrient additives after they grow two to three sets of leaves. Each additive brand varies in when you can add it, ranging from one week after germination to during the seedling stage. If you thoroughly follow instructions, you’ll prevent nutrient burn and produce a healthy harvest.

Key Nutrient Additives

Let’s explore which nutrient additives benefit cannabis growth. We’ll look at NPKs, vitamins, and healthy bacteria to keep your harvest healthy.


Macronutrients are the MVPs for every healthy organic soil system when growing cannabis plants. Nitrogen (N), phosphorus (P), and potassium (K) require the largest quantities due to their potency. Nitrogen is essential for chlorophyll, which helps cannabis grow throughout every stage, and amino acids to develop a strong foundation.

Phosphorus plays a significant role in photosynthesis, respiration, cell division, and energy-water storage. It’s essential for plant maturity and growth, but excessive amounts can be toxic to the soil system. Lastly, potassium regulates salt and water levels to prevent wilting while assisting photosynthesis and energy transfers.

Ascorbic Acid (Vitamin C)

Just as vitamin C is healthy for humans, it’s also a wonderful additive for cannabis. Ascorbic acid is commonly believed to build heavier and tighter buds that act as a powerful antioxidant. You can blend it with molasses, fructose, and other sugars in nutrient solutions applied during the last few weeks of cannabis growth.

Salicylic Acid

Salicylic acid is a naturally occurring hormone that speeds up the natural systemic acquired resistance (SAR) within plants. It can reduce the inclusion of pesticides but will block Abscisic acid (ABA), allowing plants to return to normal after stressful periods. Ensure that you spray, soak, or add Salicylic acid to compost or root hormones for a healthy harvest.


While many people think all bacteria are harmful to plants, they can be extremely beneficial additives in organic gardening, especially for cannabis growth. They can produce healthier, more robust growth in cannabis plants and are commonly used in growing rhizobacteria and mycorrhizal fungi. In addition, beneficial bacteria allow for a cannabis harvest with microbes such as endomycorrhizal fungi, ectomycorrhizal fungi, and other bacterial microorganisms.
