Watering, Feeding & Nutrients
Nutrient
Nutrients are essential elements that cannabis plants absorb to grow, develop, and stay healthy. Without the right nutrients in the proper balance, plants cannot perform basic life functions.
What Nutrients Do for Plants
Nutrients are chemical elements required by plants to carry out vital biological processes such as growth, energy production, and reproduction. In cannabis cultivation, nutrients are delivered primarily through the growing medium and water, where they are absorbed by the roots and transported throughout the plant.
Types of Plant Nutrients
Plant nutrients are commonly divided into macronutrients and micronutrients. Macronutrients are needed in larger amounts and include nitrogen, phosphorus, and potassium, which directly influence leaf growth, root development, and flower production. Micronutrients are required in much smaller quantities but are equally important, supporting enzyme function, photosynthesis, and overall metabolic activity. Even a minor imbalance in micronutrients can lead to visible health problems.
How Nutrients Work Together
Nutrients do not work in isolation. Each element plays a specific role, and proper plant health depends on maintaining the correct ratios between them. For example, nitrogen drives leafy growth during early stages, while phosphorus and potassium become more important during flowering. If one nutrient is missing or unavailable, other nutrients may not function correctly, even if they are present in sufficient amounts.
How Plants Absorb Nutrients
From a biological perspective, nutrient uptake depends on root health, oxygen availability, and water movement. Roots absorb nutrients only when they are dissolved in water, which is why proper watering practices are closely tied to nutrient availability. Factors such as pH levels, temperature, and growing medium structure can affect whether nutrients remain accessible or become locked out.
Common Nutrient Problems in Cannabis
In cannabis cultivation, nutrient issues are among the most common challenges growers face. Deficiencies occur when a plant does not receive enough of a specific nutrient, while toxicities develop when too much is present. Both conditions can reduce growth, damage leaves, and lower yield if not corrected. Successful nutrient management involves understanding plant needs at each growth stage and adjusting feeding practices accordingly.
