Problems with cannabis cuttings: How to easily recognize and fix them

Cannabis cuttings are a great way to save a lot of time (compared to germination from Cannabis seeds ). However, some challenges can also arise. For example, yellow leaves , the The cannabis cutting is drooping . aborted or twisted ankle .

Here you'll learn how to identify the most common problems and how to solve them step by step to obtain healthy cuttings. Whether you're a beginner or advanced gardener, these practical tips will help you optimally care for your cuttings.

1. Cannabis cutting has yellow leaves

Yellow leaves on cannabis cuttings often indicate problems with nutrients, water, or light. Identifying the exact cause is crucial for successful treatment.

Causes:

• Nutrient deficiency : A lack of nitrogen or other essential nutrients can cause the leaves to turn yellow. In this case, the cutting draws nutrients from the leaves to support root growth.
• Overwatering : Too much water prevents the roots from getting enough oxygen and hinders nutrient uptake. This can also cause yellow leaves.
• Lack of light : If the plant does not receive enough light, it cannot use its energy efficiently, which also leads to yellow leaves.

Solution for yellow leaves:

• Optimize nutrient supply : Check that you are providing your cuttings with a suitable nutrient solution. For the first few weeks after taking cuttings, use a weak fertilizer solution specifically formulated for cuttings. Products with low nitrogen content and root stimulators are ideal. When planting cuttings, be sure to use only lightly fertilized soil, especially when they are still young.
• Adjust your watering habits : Check the potting mix regularly. Water only when the surface is slightly dry. Ideally, use a simple moisture meter or a wooden stick to test the moisture at the bottom of the pot. Use well-draining soil or coconut coir to prevent waterlogging. A watering method that distributes moisture evenly can help control the problem. More information is available here. Care of cannabis cuttings
• Adjust lighting conditions : Cuttings need about 18 hours of light per day. If your light source is too far away, adjusting the height or adding an extra light source will quickly improve the situation. Use an LED lamp or fluorescent tubes specifically designed for growing plants.

2. Cannabis cutting is drooping

A drooping head on a cutting indicates stress. This can be caused by lack of water, overwatering, or unfavorable temperature conditions.

Causes:

• Lack of water : A cutting that does not receive enough water will droop because the plant cannot maintain the turgor pressure (the water pressure in the cells).
• Overwatering : Too much water causes the roots to "drown" and the plant can no longer absorb nutrients. As a result, it appears limp and weakened.
• Temperature fluctuations : Extreme temperatures – whether too hot or too cold – can stress the plant and cause it to droop.

Solution:

• Balancing the water supply : First, check the moisture level of the substrate. If it's too dry, water the cutting slowly but evenly. Avoid overwatering. Lightly misting the leaves can also help refresh the plant, especially in high temperatures.
• Improve air circulation : Ensure your growing area is well-ventilated. Fresh air helps maintain a constant temperature and humidity, which strengthens the cutting. An ideal temperature is 20-25°C and a humidity level of approximately 60-80%.
• Provide support : If the cutting is already weak, you can stabilize it with a support stake or a piece of wire. Be careful not to tie the cutting too tightly to avoid further damage.

3. Cannabis cutting broken/bent over

It happens faster than you think: One careless handle or insufficient stabilization and the cutting breaks or bends.

Causes:

• Mechanical stress : Excessive pulling when repotting or tying the plant can lead to breakage.
• Insufficient structure : Cuttings that receive too little light or nutrients often develop thin stems that can easily break or bend.

Solution:

• Saving broken cuttings : If a cutting has broken off, you may still be able to save it by recutting it and replanting it immediately. Dip the freshly cut end in rooting hormone and place the cutting in fresh, moist potting mix. Then cover the cutting with plastic wrap or use a mini-greenhouse to retain moisture until new roots have formed.
• Supporting bent cuttings : If the cutting is only bent, you can straighten it by carefully attaching it to a plant stake. Use soft ribbons or plant wire to support the stem without damaging it. After a few days, the cutting should be stable again.
• Preventive measures : Ensure your cuttings receive sufficient light and are placed in a well-ventilated, but not drafty, area. This will help the stems grow stronger and more resilient.

4. Cannabis cutting has drooping leaves

Drooping leaves are a common problem and often indicate stress. It's important to identify the cause in order to act quickly.

Causes:

• Overwatering : As mentioned before, too much water means that the roots can no longer absorb nutrients, which weakens the plant and causes the leaves to droop.
• Low humidity : Cuttings need high humidity, especially in the initial stages. Air that is too dry draws moisture from the leaves, causing them to droop.
• Heat stress : Excessively high temperatures throw the plant off balance, and it tries to protect itself by drooping its leaves.

Solution:

• Adjust watering : If the substrate is too wet, let it dry out well before watering again. Use seedling pots with drainage holes so excess water can drain away.
• Increase humidity : Use a mini-greenhouse or place a clear plastic bag over the cuttings to retain moisture. Alternatively, you can place a humidifier nearby to raise the ambient humidity to 60-80%.
• Regulate the temperature : Ensure that the temperature remains constant between 20-25 °C. If temperatures are too high, you can carefully ventilate the growing area or use fans to prevent overheating.

5. Cannabis cutting sprouts

Asparagus growth means the cutting is long and thin, indicating a lack of light. This weakens the plant and should be remedied quickly.

Causes:

• Lack of light : The cutting stretches upwards because it is trying to get more light. If the light source is too far away or too weak, the plant will grow unnaturally tall.

Solution:

• Increase light intensity : Move the light closer to the cuttings, but not too close to avoid burns. A distance of 20-30 cm is ideal, depending on the type of lamp. Use high-quality plant lights such as LEDs or special fluorescent tubes optimized for growth.
• Adjust the light cycle : Cuttings need at least 18 hours of light per day. Make sure the light cycle is set correctly and the plants receive enough light. If you have several cuttings, ensure they all receive light evenly.

6. Cannabis cutting is not growing / has stopped growing

If your cutting is not growing or is growing very slowly, this could indicate various factors such as incorrect substrate, insufficient nutrients or too little light.

Causes:

• Incorrect substrate : A substrate that is too dense prevents root formation and therefore growth.
• Nutrient deficiency : A lack of nutrients can inhibit growth.
• Lack of light : Here too, light is an important factor for healthy growth.

Solution:

Use a well-draining substrate to provide the roots with sufficient oxygen. Ensure a balanced supply of nutrients and provide enough light.

7. Cannabis cutting too long / falls over

A cutting that is too long can become unstable and fall over. This is often due to insufficient light or improper care.

Causes:

• Lack of light : Just like asparagus, the cutting grows upwards in search of light.
• Incorrect handling : If the cutting is too long, it needs support to remain stable.

Solution:

Ensure the light source is close enough to the cutting and use supports to give it stability. If necessary, trim the tip to encourage growth and make it stronger.

Conclusion

Caring for cannabis cuttings can be challenging, but with the right tips and tricks, you can quickly resolve most problems. Pay attention to the correct light intensity, a balanced supply of nutrients, and proper watering. If you follow these points, your cuttings should grow healthy and develop into strong plants.
