Root Rot

Overwatering

To address root rot, first, allow the soil to dry out by reducing your watering frequency. Ensure your cannabis plants are in well-draining soil and containers with adequate drainage holes. If the plant is severely affected, consider gently removing it from its pot, trimming away any black, mushy roots, and replanting it in fresh, sterile soil. Improving air circulation around the plants can also help prevent the conditions that favor root rot development.

Wilting and Drooping Leaves

Underwatering

To address underwatering, it's crucial to establish a consistent watering schedule that meets your cannabis plant's needs, which can vary based on the stage of growth, size of the plant, and environmental conditions. Begin by slowly increasing water frequency, ensuring the soil is moist but not waterlogged. Use pots with good drainage and consider the use of a soil moisture meter to better gauge the plant's watering needs. Adjust your watering practices as the plant grows and as seasonal changes affect the plant's water consumption.

Spider Mites

Tiny spider-like pests that feed on the sap of cannabis plants, causing yellow, speckled leaves and potentially leading to plant death if not controlled.

To combat spider mites, start by isolating infected plants to prevent spread. Increase humidity around the plants as spider mites thrive in dry conditions. Use a strong stream of water to dislodge the mites from the plant. For severe infestations, apply neem oil, insecticidal soaps, or introduce predatory insects like ladybugs that feed on spider mites. Regularly inspect your plants for signs of return and maintain a clean growing environment to prevent future outbreaks.

Powdery Mildew

Fungal infection

To combat powdery mildew, start by increasing air circulation around your plants and reducing humidity levels in the grow area. It's crucial to remove and destroy any infected leaves or plants to prevent the spread. For prevention and treatment, apply a mixture of water and baking soda (1 teaspoon of baking soda per quart of water) or neem oil, both of which are effective natural fungicides. Ensure to regularly inspect your plants, especially under the leaves, to catch any early signs of infection.
