What it looks like
Leaf TIPS turn yellow then brown and crispy, often with a burnt look that creeps inward. Tips may curl. Starts on the newest, most actively-fed growth when feed is too strong.
Symptoms
- Brown/burnt crispy leaf tips
- Yellowing creeping in from the tip
- Tips curling or twisting
- Dark green leaves overall (often over-fed)
Causes
- Nutrient solution too strong (high EC/PPM)
- Too-frequent feeding
- Hot/over-amended soil
- Cal-mag or supplement stacking pushing EC up
How to fix it
- 1Flush with pH'd plain water to bring EC down
- 2Resume feeding at LOWER strength (cut 25–50%)
- 3Trim only the worst-burnt tips; the damage won't heal but new growth recovers
Prevention
- Start feeds at half strength and ramp up watching the tips
- Measure EC/PPM rather than guessing
- Ease off at the first hint of tip burn
悟る · how satoru tells it apart
Tip burn from overfeeding vs. light burn vs. potassium shortage look similar but need opposite responses. Satoru checks your logged feed strength and light height before recommending flush-vs-feed.
Commonly confused with: Potassium Deficiency, Light Burn, Nitrogen Toxicity.
