Definition
Wind Burn – Autopot
Wind burn is mechanical/environmental stress from excessive direct airflow that damages leaf edges and can mimic nutrient or heat injury. This page emphasizes Autopot decision support for cannabis cultivation. Context focus: Autopot production constraints and controls.
Why this matters: Use this page to compare lookalikes, verify visual patterns, and choose the safest next checks before changing inputs.
Symptom checklist
- • Leaf edges dry or curl in zones facing direct fan flow.
- • Pattern matches airflow direction rather than nutrient sequence.
- • Damage is often localized to fan-facing rows or levels.
- • Young tissue can deform under sustained blast exposure.
- • Symptoms persist until airflow distribution is corrected.
- • Edge desiccation, curl, and localized tissue roughening.
Likely causes
- • Direct high-velocity airflow at close range.
- • Poor fan angle/placement causing concentrated blast zones.
- • Insufficient airflow mixing leading to local turbulence stress.

Confirm steps
- • Map symptom rows against fan positions and airflow direction.
- • Adjust airflow and observe symptom stabilization over 48-72h.
- • Capture before/after photo comparisons from fixed points.
What to do now
- • Redirect or diffuse direct fan blast from sensitive canopy zones.
- • Rebalance airflow for uniform movement rather than focused jets.
- • Avoid simultaneous major feed changes while airflow is being corrected.
- • Prioritize corrective actions compatible with Autopot workflows.
Prevention
- • Perform airflow walkthroughs at full canopy density.
- • Use distributed airflow instead of single high-velocity streams.
- • Re-check after canopy height and pruning changes.
- • Embed Autopot-specific monitoring checkpoints in weekly QA.
Lookalikes and how to tell
- light burn: Compare symptom location, speed of progression, and tissue type before selecting a likely cause.
- heat stress: Compare symptom location, speed of progression, and tissue type before selecting a likely cause.
- nutrient burn general: Compare symptom location, speed of progression, and tissue type before selecting a likely cause.
- potassium: Compare symptom location, speed of progression, and tissue type before selecting a likely cause.
FAQ
What is the first thing to check?
Verify the strongest visible pattern and where it starts (new growth, old leaves, canopy zone, or root zone).
What if multiple causes seem possible?
Run lookalike checks and prioritize the fastest, lowest-risk confirmations before changing feed or environment.
When should I upload photos?
Upload when the pattern is unclear or mixed so you can get evidence-quality feedback plus the most relevant guides and compare links.

Stage notes
- Seedling: If seen in seedlings, prioritize gentle corrections and close monitoring.
- Veg: Veg stage benefits from repeat observation to confirm progression direction.
- Flower: Flower stage requires balancing correction speed with quality protection.
- Drying: For post-harvest stages, use strict handling and spacing controls.
Medium notes
- Soil: Watch dry-back consistency and root-zone aeration.
- Coco: Track fertigation rhythm and runoff trend stability.
- Hydro: Prioritize reservoir hygiene and oxygenation stability.
- AutoPot: Verify valve behavior, filtration, and line balance.
- Living soil: Avoid abrupt chemistry swings and maintain moisture rhythm.
