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 common

Signs

  • 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.
