Burnt or crispy cannabis leaf tips: compare feed, roots, light, and heat
Dry brown tips and edges are easy to label and hard to explain from appearance alone. Record where they occur, whether damage is progressing, and what changed before comparing feeding, root-zone, light, and heat evidence.

Swipe horizontally, or focus this table and use the arrow keys, to compare all four evidence columns.
| Visible pattern | Evidence to compare | What to log next | What not to assume |
|---|---|---|---|
| Burnt, crispy, or damaged tips | Affected position, Feed history, Root-zone history, Light and heat | Affected canopy position, progression, repeatable photos, and any measured input or room change. | Crispy tips alone do not prove nutrient burn or excess light. |
Separate exposed zones from whole-plant patterns
Record whether damage is concentrated at the highest canopy, at leaf edges across the plant, on older growth, or near a local hot or dry pocket. Compare affected and shaded tissue and note whether new growth is stable after the observation.
Compare feeding and root-zone evidence
Review the same plant's input EC and pH, runoff EC when recorded, watering volume, timing, drainage, and dryback or substrate observations. Tip damage alone does not prove excess nutrients, and an absent runoff record is not a zero.
Compare explicit light and heat context
Look for a documented fixture, dimmer, distance, PPFD, schedule, canopy-growth, temperature, humidity, or airflow change. The word light in unrelated notes is not lighting evidence, and room temperature alone may miss a canopy hot spot.
Avoid stacked corrections
Avoid changing feeding, watering, lighting, and airflow at the same time. Preserve a baseline, change one justified variable, and record the response.
