Marijuana, like many other plants, comes with a couple of challenges. As a result, there are times one might experience reduced yield or poor-quality leaves. Many things could be responsible for this, like poor conditions, nutrient deficiency, excessive moisture supply, insects, etc. Failure to identify and take care of these could threaten and translate to a problem for the plant.
Even at times when you make the conditions favorable, some problems could still spring up. This is because it can be tricky to grow marijuana. It is a sensitive plant by nature, requiring proper diligence from seedling to harvesting. However, the responsibility lies on you as the grower to identify any problems and handle them before affecting the plant.
Here are five common problems one might experience during the lifestyle of a typical marijuana plant.
Yellow Tips on Leaves
If you notice that the tip of your plant is turning yellow, it is called nutrient burn. This happens when the plant gets excessive nutrients too often. You will likely notice this at the tip of the leaves, and with time, it will turn brown, giving a burnt appearance. As a result, your marijuana plant’s yield will drastically slow down, which will lead to a loss of nutrients.
The remedy is to completely stop giving the plant any nutrients for up to two weeks. With this, the plant gets enough time to discharge all excessive nutrients. Also, ensure only to use nutrients specified for the marijuana plant and follow the recommended direction of feeding the plant as specified on the package.

The leaves will feel firm while every part, including the tip, will appear curled down. This is often the aftermath of giving the plant too much water or when you overwater it. Fixing these cannabis plant problems simply involves giving intervals between the watering period. After that, water gradually until the leaves assume a normal look. People planting from a pot should ensure that the water can drain from the bottom.
Also, marijuana plants are best watered when the topsoil is very dry. When watering, 20% of the extra water should flow off the containers’ bottom before you stop. Do not water again until the topsoil is dry
When your plant does not get enough nutrients, it causes stunted growth, which affects yields. Majorly, this happens when there is an unbalanced soil pH which affects the life of the plant. Boron deficiency in a marijuana plant will appear via stunted growth in the upper leaf parts. As a result, it will be small with a generally unhealthy appearance. Make sure to check boron deficiency on time to avoid plant death.
The remedy for this is to rectify the soil’s pH and make it favorable. Since this is due to the low pH of the soil, take steps to get the pH to the right level by considering soil rich in an essential nutrient that is primal to its growth.
Giving your plant excessive nitrogen is a problem, the same way it will react negatively to nitrogen deficiency. With excess nitrogen, expect signs like dark green leaves, retarded growth, and weak stems. Affected plants will have their leaves curl inward. Over time if this is not corrected, it will turn yellow, leading to the death of the plant. With heat and unstable pH, this problem can affect your entire marijuana farm.
This problem is traced to excess nitrogen, making it essential to consider the nitrogen present in your nutrient. It is a problem that calls for being strategic with the nitrogen content. During the vegetative stage, nitrogen is pretty important, with less of it in the flowering stage. As a result, you will need a nutrient with a high nitrogen solution in the vegetative stage and switch to a nutrient with lower nitrogen content in the flowering stage. With this, you can maintain the right nitrogen level.

Without a doubt, your marijuana plant needs enough light for proper growth and yield, but the excessive plant could be harmful as well. When you expose the plant to extreme sunlight for a long time, it causes a light burn, affecting indoor strain.
This happens when you see yellow leaves appearing under growth light which could be curling up. Your marijuana plant does not need excessive light as too much light will make the leaves turn yellow at the source of light. Light burns can be fixed easily without a lasting effect on the plant. Here are two common reasons for light burns:

- The light source is excessively close to the plant
- The light bulb has an extreme intensity, too much for the plant to handle.
With this, you can quickly fix a light burn by moving the light up away from the tip of the plant. If this seems impossible, use a bulb with lower intensity. For plants grown outdoors, avoid exposing them to too much sunlight.
Growing marijuana is pretty tricky, so you can expect many issues as the plant grows. However, discussed here are a common problem faced by growers alongside the best approach to take care of them.
