Yellow or Burnt Leaf Tips on Cannabis
Yellow or brown-tipped cannabis leaves are almost always nutrient burn. The fix is to feed less.
What it looks like
- ●Tips of leaves yellow or brown and crispy
- ●Burn advances inward from the very tip
- ●Upper leaves affected worst (newest growth)
Quick diagnostic checks
1If tips are crispy, flush and reduce feed strength
2New growth will come in clean — old burn doesn't heal
Causes ranked by likelihood
1. Overfeeding
Most commonSigns
- ●Following bottle dose (usually too strong)
- ●Dark green leaves
Fix
- ✓Flush with 3x pot volume of pH 6.5 water
- ✓Feed at 50% strength going forward
- ✓Cannabis likes LESS nutes than you think
⚠️When to worry
Progressive tip burn (more than ⅛" per week) = ongoing overfeed. Adjust and monitor.
