On marijuana (cannabis) plants, several mite species are notorious for causing infestations. The most commonly encountered include:

### 1. **Two-Spotted Spider Mite (*Tetranychus urticae*)**

* The most widespread and destructive mite pest in cannabis cultivation.
* Recognizable by their tiny size (about 0.5 mm) and ability to produce fine webbing on leaves.
* Damage appears as stippling (tiny yellow or white spots), leaf yellowing, and eventually necrosis.

### 2. **Broad Mite (*Polyphagotarsonemus latus*)**

* Much smaller than spider mites (often requiring a microscope to detect).
* They cause leaf twisting, blistering, and distorted new growth.
* Infestations often mimic nutrient deficiencies or viral infections.

### 3. **Hemp Russet Mite (*Aculops cannabicola*)**

* A cannabis-specialist eriophyid mite, extremely small and nearly transparent.
* They tend to feed on stems, petioles, and flower tissues rather than just leaf surfaces.
* Symptoms include leaf curling, bronzing, reduced vigor, and poor bud development.

🔑 **Summary:**

* **Most common overall:** *Two-Spotted Spider Mite*
* **Most damaging to new growth:** *Broad Mite*
* **Most cannabis-specific:** *Hemp Russet Mite*

Would you like me to also include **less common mites** (like cyclamen mites or other tarsonemids) that occasionally show up in indoor cannabis grows, or should I focus only on the main three threats?
