Why Are My Marijuana Plants Turning Yellow?
If you’ve ever wondered why your marijuana plants are turning yellow, you’re not alone. Many growers are wondering the same thing. It’s no fun to see your precious marijuana plants in a sad state. This can be caused by a number of factors, including improper light placement or too much nitrogen. Here’s what you need to know.

The most common cause of yellow leaves on your marijuana plants is a lack of key nutrients. Without these vital nutrients, your plants’ leaves will become discolored and begin to wilt. A deficiency will disrupt their growth cycle and prevent them from carrying out their functions. Similarly, too much nitrogen can burn your cannabis plants’ leaves and cause them to turn yellow. This occurs after the sixth week of flowering.
Another cause of yellow leaves is underwatering. Insufficient water can cause leaves to yellow, because plants use the water potential to pull moisture up into the leaves and stems, which are vital for photosynthesis. Without enough water, the tips of the leaves will curl downward and take on a claw shape. Ultimately, your plant will die. In such a case, it’s time to change the way you care for your marijuana plants.
Overwatering is also a common cause of yellowing marijuana plants. If you’re growing marijuana in a container, you need to make sure you’re providing sufficient moisture in the soil. Water your plants only when they need it. Don’t overwater them. This could cause them to become dehydrated. A solution to this problem is adding nitrogen-rich plant nutrients to the soil or transplanting the plants. Once you’ve solved the problem, you can expect your plants to start blooming and looking healthy again!
If your cannabis plants are turning yellow near a light source, you may need to adjust the light. During long periods of time, cannabis leaves may become yellow from light burn. If this occurs, you can try moving them 8-20 inches away from the light source. You can also add acid to correct the pH level to your plant’s drinking water. This can also be a good way to reduce the risk of your cannabis plants turning yellow.
If you’re growing cannabis in a grow container, you should keep it between 70 and 80 degrees Fahrenheit. Too cold can cause yellowing leaves, so it’s important to keep the soil warmer during the night. Root insulation is also important. If you have a cold floor, you should place the plant on a bucket or stool instead of the floor. If you see yellow leaves near the soil, they’re suffering from nutrient deficiency. Use a cannabis-specific fertilizer to correct the problem.
Another reason for yellowing cannabis leaves is improper soil pH. A soil pH of 5.5 to 6.5 is ideal for healthy cannabis plants. If your soil pH is lower than this, you can purchase a soil pH test kit. These are inexpensive and easy to use, but they don’t test for calcium carbonate, which has a pH of 9.9! If you’re growing in soil, you can also test your soil for calcium carbonate by soaking a few leaves in vinegar.
