When you see the edges of the leaves curving, the cause is usually that the light is too close. It can be caused by both light stress and heat. Occasionally, it's also due to cold or watering problems, especially when a plant is cold and overwatered. Heat stress can occur indoors or outdoors.
If you see curly, unsightly looking brown fringes, your cannabis leaves are sending you a distress signal. Cannabis plants can photosynthesize efficiently at moderate temperatures of up to 28°C. Any temperature above 30°C and your plants will be in the danger zone. Combine this with low relative humidity and you'll have real problems.
New leaves will grow twisted and old leaves will curl yellow and may even burn to a crisp, rusty brown. The last thing growers want to see is their cannabis leaves being rolled up or canoed down. While this problem can be the result of several factors, the fact that cannabis plants themselves have more than 90% water is often revealing. Irrigating the crop too much or too little is the most likely reason for curling weed leaves.
However, don't jump to conclusions right away, because some old marijuana leaves curl naturally. If the entire plant is affected, you should take immediate action. Growing indoors or outdoors makes a big difference in your options if you have rolled up cannabis leaves. Indoor growers can use heaters or insulators, but increasing the number of lights would also help.
Too much water is the most likely culprit, but insufficient watering can cause similar symptoms. Exaggerating nutrients is a common offence, while deficiencies can also cause cannabis leaves to curl. Curly cannabis leaves are due to many different problems your marijuana plants might be experiencing. Heat stress and minor burns can sometimes go hand in hand, but you can still find minor burns even at ideal temperatures.
Light burning is more common in indoor installations, usually when plants are too close to grow lights. Like heat stress, curling usually occurs toward the top of the plant or in the part that is closest to the light source. With a slight burn, the leaves will start to turn yellow and eventually curl. If it's a minor burn, move the plants away from your light source and they'll recover.
The first step in determining the source of curly leaves is to make sure you don't overwater. Excessive watering puts the plant at risk of drowning and rotting its buds, as well as providing the perfect setting for Pythium, the parasite that causes root rot. Cannabis leaves curl due to waterlogging and rotting. Cannabis seedling leaves that curve downward stress both the grower and the plant, and it is vital to make a correct diagnosis.
Although cannabis plants are not able to vocalize help when they need it, they will send you some signals to tell you that everything is fine. Scratching or curling leaves is one of the most common difficulties most people have with cannabis plants. These plants grow easily indoors and outdoors with award-winning genetics, fewer curly cannabis leaves and a delicious flavor profile. When the environment is too hot for a cannabis plant, you'll start to notice curly leaves, among other things.
Growers should rinse the roots with water to remove excess nutrients and solve the problem of curling the leaves in the pot due to excessive fertilization. The same applies to the flowering phase, when excess phosphorus or potassium causes cannabis leaves to twist.
