Hemp russet mites are tiny bugs that infest cannabis plants, often residing in the crevices of leaves, stems, or buds. They are difficult to spot unless there is a significant infestation. Initially, the symptoms may be mistaken for other issues like mold, pollen, or nutrient deficiencies. The leaves may exhibit curling on the edges, and buds can start to wither. The mites themselves appear as beige or yellow masses, usually concentrated towards the top of the plant. An intense infestation can cause the affected parts of the cannabis plant to turn beige or yellow. Infected plants may also experience drooping, dull-colored leaves and stems, as well as the presence of brown or yellow spots. Identifying hemp russet mites can be challenging due to their microscopic size.

Cause of Issue
◉ Hemp russet mites can reproduce and attack cannabis plants throughout the year, most harmful during the flowering stage. ◉ Indoors, fans can inadvertently spread the mites. ◉ The pests lay their eggs inside the plant, making complete elimination challenging.
Symptoms
◉ Symptoms are often more pronounced at the top of the plant. ◉ The mites themselves are pale, typically tan or yellow, and may cause the plant to appear beige or yellow in heavily infested areas. ◉ They can be mistaken for fungus, mold, or pollen. Drooping of the tops of the plants is common in severe infestations. Curling of the leaf edges may occur in some plants. ◉ Affected areas of the plant may exhibit dull coloration, brittleness, and serve as habitats for the mites. ◉ Brown or yellow spots on the leaves result from leaf stress and are not visible bites. ◉ Identifying individual mites can be challenging due to their small size.
Corrective Actions
◉ Starting from seeds can prevent mites and their eggs from surviving on the plants unless introduced from another source. ◉ Treating and quarantining new plants, even seemingly healthy ones, helps ensure they are free from hemp russet mites. ◉ If the infestation is severe, removing and treating the affected plants, thoroughly cleaning the growing area, and starting anew may be necessary. ◉ Regular treatments may be required, potentially several times a week or even daily, depending on the severity of the infestation. ◉ Spraying treatments should be done before the lights go out to minimize the risk of plant burn. ◉ Following instructions on product labels is crucial for effective treatment and to avoid complications. ◉ After eliminating the mites, continuing treatment with different products for at least five additional weeks can prevent a resurgence of the infestation. ◉ Please note that these solutions are provided for informational purposes and should not replace professional advice.
