Wilting can be as a result of poor watering practices; you are either adding too much water for your plants or too little water. Too much water results in your plant’s roots rotting and disrupting the uptake of water and minerals by the plant. Therefore, your plant leaves start to wilt or droop and die. Drooping leaves may seem hanging.

2. Yellow Leaves 

Sometimes, when your cannabis plants are almost mature for harvesting, their leaves have a tinge of yellow.

Why are the leaves turning yellow? Well, this is mostly as a result of excessive lighting and heat, causing stress on your plants. Using lighting that emits extreme light on your plant in indoor farming or excessive sunlight and warmth for your outdoor plants have the same effect.

Once you identify such a problem, you can improvise and provide shade for outdoor farming. For indoor plants, reduce the wattage and keep the lighting a bit farther away from the plants. However, continue monitoring your plants to ensure that they are reviving, and the light is not too far away, which may result in a light deficiency. 

3. Spots on the Leaves 

Spots on plant leaves can translate to many different crop situations.

If bright yellow or has some yellow coloring on the leaf veins, then your plants lack iron and magnesium systematically. If dark green on the lower leaves with others turning yellow, the plant is phosphorus-deficient. If it has little or no potassium, then the leaves turn brown with burns on end.
