There is only so much light your marijuana plant can take. At some point, the plant will show evidence of strain around the main points where it receives light. Brown or yellow spots will show up on the leaves, followed by burnt tips and the borders will remain green.
In the spots where it’s getting an excess of light, the leaves will look burnt. Learn how to identify and prevent light burn on your marijuana plants
What is light burn
Your buds can turn albino through light bleaching. This frequently happens with high-power LEDs and HPS lights that are placed too close to the top of the plant. As a result, your plant gets way more light than it needs.
Once your buds are burnt, their strength diminishes and may get to the point to where it has no THC. So, the moral of the story is: make sure you don’t give them too much light to prevent any bleaching.

How to fix light burn
If you think the plants are getting more light than is necessary, start by sliding the grow light farther from the top of the plants.
Light bleaching because of sunlight is very rare when outdoor growing and there is no way they will ever get too close to the sun. If you move your plants from a bad situation, then into the sun they may display sign of light bleaching if they never had a chance to adjust to the increase in light.
Take it slow when adjusting your plants conditions. You don’t want to stress your plant out for either outdoor or indoor growing.
Maintain a cozy temperature consistently for the best results and health. Think about it like this, if you feel like it’s too hot, then certainly it’s too hot for the plants. Things aren’t as simple for outdoor growing, but take the time to learn what to do for outdoor heat.
