Leaf Tip Burn After Feeding Cannabis
Leaf Tip Burn After Feeding Cannabis usually shows up when the last feed landed too hot for the current root zone, salts were already stacked in the medium, or pH drift turned a normal feed into tip burn. Compare the timing against the last irrigation, runoff strength, and whether the burn is limited to fresh tips or spreading down the leaf edges.
Leaf tip burn after feeding cannabis? Check for excess EC, salt buildup, pH drift, and the fastest next inspection points.
Common Causes
- EC was too strong for the plant size or recent dry-back
- Salt buildup in the medium made the next feeding hit harder
- Runoff pH drift pushed the feed outside the clean uptake range
- Heat or low humidity increased transpiration and concentrated the feed response
How to Tell Which One You Have
Leaf Tip Burn After Feeding Cannabis is most convincing when the damage appears shortly after feeding, starts on the very tips, and lines up with high runoff EC, crusted salts, or a recent feed increase rather than random spotting across the canopy.
FAQ
Does tip burn after feeding always mean nutrient burn?
Not always. It can also happen when salts were already accumulated in the pot or when pH drift made an otherwise normal feed harder for the roots to process.
What should I check first?
Check the last feed strength, runoff EC and pH, pot dry-back, and whether the damage is confined to the newest tips or marching across older leaves too.
Should I add more nutrients to fix pale leaves at the same time?
Usually no. Confirm the root-zone readings first, because adding more feed into a salty or unstable medium often worsens the tip burn.
