How to Spot and Treat a Light Burn on Your Cannabis Plants
Light burn is the yellowing of your plant leaves as a result of excessive lighting saturation or proximity of the plant to the light source which puts some stress on the leaves closest to the source of light. Light burn is said to share symptoms with nitrogen deficiency which also causes yellowing of the leaves though they start from the bottom of the leaves and fall off the plant easily. But with a light burn, the leaves typically start pointing upwards, grow pale, and then start turning yellow though the insides veins remain green and don’t fall off the plants easily. Light burn does not only cause your leaves to yellow but can also turn them white and brown tips to give them a ‘burnt’ look.
