Tip Burn

Tip Burn in cannabis refers to the discoloration and necrosis of the tips of the plant leaves, which can often extend to the edges of the leaf. This condition is indicative of nutrient burn, usually caused by over-fertilization — an excess of certain nutrients, particularly nitrogen, potassium, or phosphorus.

The plant’s inability to absorb the overwhelming amount of nutrients results in what looks like burnt leaf tips, hence the term.

Progression and Effects

What usually starts as slight yellowing or browning at the tips can progress, causing the affected leaves to curl, become brittle, and potentially stunt the plant’s growth if not addressed promptly. Tip burn is a common issue for both novice and experienced cannabis growers alike, as it can also be triggered by fluctuations in pH levels or inadequate water quality.

Prevention and Remedy

Correcting the nutrient concentration, ensuring proper pH balance, and using filtered water can typically prevent and remedy tip burn.

Importance of Early Detection

An early detection of tip burn is crucial to the health of a cannabis plant because if left unchecked, it can lead to a more serious condition known as ‘nutrient lockout,’ where the plant becomes unable to absorb any nutrients at all. Cannabis cultivators should monitor their plants regularly for signs of tip burn as part of their plant care routine.

Consequently, a key component of effective cannabis cultivation lies in mastering the delicate balancing act of nutrient supply, thereby preventing damages such as tip burn that can compromise the quality and yield of the crop.
