What Causes Curling Cannabis Leaves?


One of the most common reasons for cannabis leaves to curl is overwatering. When a plant is overwatered, the stem snaps and then curves when drying out afterward.

This can cause the leaves to curl or cup, as well as brown spots on the leaves and unusual leaf discolorations.

If you think your plant may be overwatered, the best course of action is to let the soil dry out completely before watering again.

If the leaves are still curling after you’ve corrected the watering schedule, it’s possible that root rot has set in and the plant will need to be repotted with fresh soil.

Nitrogen deficiency

If your cannabis plant is young or hasn’t been flowering for long, chances are it’s a nitrogen deficiency causing the problem. You can tell which problem a curvy cannabis plant has by its leaves.

In general, if the leaves are young or haven’t been flowering for long, chances are it’s a nitrogen deficiency causing the problem. If the leaves are old and have been flowering for a while, it’s more likely that overwatering is to blame.


How long cannabis has been left out in light can cause it to become dry and brittle. This will lead to the leaves folding when touched. Cannabis needs proper moisture content so that it doesn’t die or get crispy.

Over-watering is one of the most common mistakes made by new growers, and can lead to a host of problems including root rot, nutrient deficiencies, and even death.

Start by giving your plants a light watering every other day, and then increase or decrease the amount as needed based on how they look. If you see any signs of wilting or yellowing, cut back on the amount of water you’re giving them.
