Foliar Feeding

Foliar feeding refers to the practice of applying liquid fertilizer directly to the leaves of cannabis plants, as opposed to the soil or growing medium. This method of nutrient delivery is particularly useful for addressing specific plant deficiencies swiftly, as it enables plants to absorb essential minerals and vitamins directly through their stomata and epidermis, leading to a faster response compared to root feeding.

When cannabis exhibits signs of micronutrient deficiencies, such as yellowing leaves or stunted growth, foliar feeding can be an immediate remedy to help revert the plant to optimal health.

In the Realm of Cannabis Biology and Science

In the realm of Cannabis Biology and Science, foliar spraying is often adopted as a corrective measure when nutrient uptake through the roots is hampered due to factors like pH imbalances, overwatering, or root damage. By strategically applying water-soluble fertilizers, growers can target the affected areas and mitigate the deficiency symptoms.

Essential nutrients like nitrogen, zinc, magnesium, and iron are commonly used in foliar solutions to treat deficiencies. This technique is particularly advantageous during the vegetative growth phase of cannabis, where rapid nutrient absorption is critical for healthy development.

Can Fertigation be used in conjunction with Foliar Feeding for plants?

Yes, fertigation in agriculture practice can definitely be used in conjunction with foliar feeding for plants. Fertigation allows for the efficient delivery of nutrients directly to the plant’s root system, while foliar feeding provides nutrients through the plant’s foliage, resulting in enhanced nutrient uptake and overall plant health.

Cautions with Foliar Feeding

Although effective, foliar feeding requires careful application to prevent overuse and potential damage to the cannabis plants. It’s important to apply the spray during the cooler parts of the day or when lights are off in indoor setups to minimize the risk of leaf burn.

Additionally, achieving a fine mist and uniform coverage ensures that all leaves receive the nutrient benefits. Growers must monitor their plants closely after foliar feeding to assess the improvement in plant health and make necessary adjustments to their nutrient management plan.
