Why Do Cannabis Leaves Turn Yellow?
What does it mean for your cannabis plant’s health when leaves start turning yellow? One of the telltale signs of a plant with health issues is the presence of leaves that turn yellow. This can happen due to a number of reasons, but mostly it is caused by incorrect environmental conditions or nutrient deficiencies in the plant's soil.
When cannabis leaves are yellowing, this could mean that the plant is not getting enough fertilizer, water or light. Moreover, as cannabis plants develop and age, they naturally tend to turn yellow towards their flowering stages. Cannabis strains also have many different colors when growing so it’s important to note that different strains may show deficiencies in different ways. Knowing what causes cannabis leaves to yellows and understanding the associated implications can help growers better care for their cannabis plants and foster healthy growth throughout their cultivation cycle.
Common Causes of Yellowing Leaves on Cannabis Plants
Yellowing leaves on cannabis plants is actually quite common and there are several potential causes. Often, it can be due to a nutrient deficiency in the soil, such as a lack of nitrogen or potassium. Improving the soil nutrition can resolve this issue. Yellow leaves can also be caused by excess light and heat. Too much UV exposure, for example, can lead to burnt-looking leaves that eventually yellow and die off. Overwatering or underwatering your plants can both increase the likelihood of yellow leaves appearing, too. Proper watering techniques—as well as monitoring of light levels and soil nutrition—are essential for preventing yellow leaves on your cannabis plants.

If you are feeling overwhelmed by the scale of the problems your plant is enduring, take a deep breath and get organized.

Be sure to double check your nutrient regimens as well. Monitoring and responding to pests, such as aphids or scales, is also important in order to maintain your plant’s health.
