How to Spot and Treat Cannabis Light Burns


Growing cannabis successfully requires a lot of dedication and immense attention to detail. Marijuana plants have distinct requirements that growers should meet to maximize their harvest. One essential factor that cannabis farmers must consider is the amount of light their crops receive.

Although light is vital for cannabis growth, it can sometimes cause more harm than good when not properly managed. Light burn on weed plants can cause permanent damage to your crops and affect the quality of your yield. This problem is mainly faced by farmers who prefer growing marijuana indoors since they have to balance a host of variables when providing light to their plants.

Nevertheless, this is a problem that you can efficiently fix, provided you spot it in time and follow the appropriate measures. Our guide explores everything you need to know about marijuana light burns to help cultivators avoid this nuisance.

Understanding Cannabis Light Burns
When cannabis plants are exposed to excessive light, particularly in the high-energy spectrum, they may suffer from light burns or light stress. This condition is also known as cannabis light bleaching and can lead to the destruction of chlorophyll within the leaves. Consequently, it can reduce the rate of photosynthesis, cause stunted growth, and even lead to crop loss.

Recognizing the Symptoms
Early detection plays a crucial role in effectively addressing light stress on plants. Still, it’s vital to remember that some symptoms of light burn cannabis can be mistaken for other weed plant issues like cannabis wind burns. Therefore, you should thoroughly examine your crops to eliminate the likelihood of other problems. Here’s what to keep an eye on to detect light bleaching weed.

Discolored leaves
The initial sign of light burns is the yellowing of leaves, often accompanied by browning edges and diminished green coloration. Even so, this is also a common sign of nutrient deficiencies in cannabis plants. Therefore, ensure that the leaves near the light source are the ones getting discolored before concluding that your plants are experiencing light burns.

Leaf deformation and dryness
Leaves may start to curl upwards or downwards and feel dry or brittle, as the plant reacts to the excessive light and heat.

Bleached Buds
One surefire indication that your cannabis plants suffer from light stress during flowering is the presence of bleached buds. If the buds of your crops are too close to the light source during the cannabis plant growing stage, they may become completely white. Although this might look like a unique design that is done intentionally by weed producers, this phenomenon often renders the bud useless.

Proactive Measures for Healthy Plants
Prevention is always better than cure. This adage is especially true when it comes to light bleaching weed. Here are some cannabis growing tips that will help you protect your marijuana crops from light stress.

Observe Appropriate Light Distance
Ensure your plants are at the recommended distance from the light source to avoid burns. For High-Intensity Discharge (HID) lights, maintain a distance of 12 to 30 inches. For LED lights, 18 to 24 inches should be adequate.

Regulate Temperature and Humidity
Optimal temperature and humidity levels are vital for your cannabis plants’ overall well-being. Invest in reliable thermometer and hygrometer tools to keep track of these elements.

How to Treat Cannabis Light Burns
If you observe light burns on your cannabis plants, don’t fret! Take these steps to help them recover:

Move impacted plants
Relocate the affected plants further from the light source, and monitor them for any improvements.

Trim damaged leaves
Remove any severely injured or dead leaves to promote new growth and redirect the plant’s energy.

Modify the environment
Make necessary changes to your grow room’s conditions, such as adjusting the light distance, temperature, and humidity. Similarly, you can try to grow weed without equipment if you have a flexible farming operation.

Bottom Line
Light burns in cannabis plants are a common but preventable challenge for growers. Our guide provides enough information to help you recognize the symptoms of light burns and has practical techniques for preventing and treating affected plants. Utilizing it will help you keep your crops healthy and maximize your yield.
