Cannabis Leaves Canoeing – #4 Key Reasons!

Cannabis leaves canoeing is a common plant health complication. Have you noticed your bud, or anyone’s plant, experiencing this issue? The leaves start curling, and the plant probably starts experiencing health issues. Have you thought of ways to stop it or even eliminate the entire plant?

Well, fret not! Why is that? We have prepared this in-depth guide to help you learn more about this issue. So, let us dive right into it!

Cannabis Leaves Canoeing – Defined

Cannabis leaves canoeing, also called curling or cannabis leaf tacoing, is a plant health complication. There are various reasons for cannabis leaves canoeing, including stress, pests, nutrient deficiencies, and environmental settings. 

It often appears in the form of leaves that curl inwards and might also be prone to distortion issues. 

The curling issue can compromise photosynthesis and reduce the light the plant can absorb. It can also cause the plant to experience complications like stunted growth. Pests like aphids can also lead to the pot leaves issue. 

Reasons For Cannabis Leaves Canoeing

There are various reasons for cannabis leaf tacoing, including:

Reason #1. Environmental Stress 

Environmental stress on cannabis plants can easily lead to the canoeing issue. Factors like excessive temperature, light, wind, and water stress are notorious for causing this issue. 

Plus, identifying the primary stressor of the canoeing issue is essential. Usually, this involves using techniques like high or low temps adjustment. 

Temperature changes, both high and low, can cause cannabis leaves to canoe. The best temperature for cannabis plants is between 70 and 80 degrees Fahrenheit. 

Temperatures that drop too low can lead to issues like plant stress, and curling leaves. High temperatures can also lead to secondary problems alongside the curling, like wilting. Too much wind can also lead to curling leaves – so be cautious.

Reason #2. Nutritional Issues 

Nutritional deficiency is another common problem that can lead to cannabis plant’s canoeing. Potassium, nitrogen, and phosphorus are common nutrients that lead to this deficiency. Nutrional issues can also occur due to excessive fertilizer usage.

Nitrogen is a potent micronutrient required for the development and growth of plants. Without it, cannabis plants become prone to issues like appearance changes and physicality. 

Phosphorous is also essential for the development of roots and leaves. Without it, indoor growers should expect plants to be prone to dull and dark colors. 

Magnesium and calcium are equally important – without them, plants experience the derided nutrient lockout. They contribute to processes like photosynthesis, which is essential in leaf production. 

Reason #3. Insect Infestation

Insects are always on all if not all, plant complication lists. Some cannabis strains are particularly prone to this issue, especially when they grow outdoors. These pests can easily break down your plant harvests when left unchecked. Some common signs of infestation include the canoeing of the leaves. 

Common insects that can be notorious for this issue include thrips, mites, and aphids. The first step in handling this issue is to identify its primary cause. 

You can start by looking physically at sections of the plant. Check for the presence of eggs or sheaths that could serve as habitats. Some insects are also camouflaged, making detecting their presence on your plants difficult. 

Reason #4. Light Stress

Light stress can also lead to the leaves forming a canoe shape. That is because plants require a delicate balance of light to ensure optimal growth and development. 

Any excessive or insufficient light can easily lead to curling cannabis leaves. The plants in the development stage are the most prone to light stress complications. The first sign the plant is suffering from the canoeing issue is the leaves might start to form a concave shape. Be keen on also whether you have a heat stressed plant.

How to Stop Cannabis Leaves Curling

There are various ways of stopping cannabis leaves from curling, including:

  1. Check Soil pH

The soil pH is an essential metric in the growth and development of cannabis. Usually, a slightly acidic pH of between 6.0 and 7.0 works best for cannabis plants. 

pH is metric referring to the acidity or alkalinity level of the soil. Using too acidic or alkaline soil can easily lead to the cannabis leaves curling issue. It compromises the nutrients in the soil, which leads to deficiencies. 

Using a testing kit is the best method to check the soil pH. It usually features a solution in that you add a soil sample from your garden. 

The color produced upon mixing the soil and the solution will reveal the pH of the soil. Adding organic amendments like compost and manure can also be practical for moderating the soil pH. It also helps improve the nutrient levels of your soil. 

It’s best to test the soil first before application. Add some lime to raise the pH accordingly. You can use either the pelletised or powdered lime form. 

Then wait for upto one week before testing the cannabis again for improper pH issues. Sulfur in granular form can also work well to help moderate the pH levels of soil. This metric is fundamental if you fall in the outdoor growers category.

  1. Check the Light Amount

Light is crucial for cannabis plants, especially if you want healthy leaves and an excellent yield. It’s also essential for stopping the curling cannabis leaves issue.

The amount of light your healthy plants receive will determine the growth, and quality of their lives. Using minimal light can cause leaves curling and lead to discoloration issues. It’s an issue people call light stress, and it can inhibit plant growth in various ways. Too much light can also lead to the curling problem.

Plus, there are various of ensuring your cannabis plants receive sufficient light. When growing outdoors, ensure you have plants that receive upto six hours of sunlight daily. Consider setting up resources like artificial lights or LED grow lights if the plants grow indoors.

The light intensity and spectrum are important metrics because they relate to the type of light you use. You may also have to adjust the height of the light fixtures and intensity to suit the growing needs of your plants. 

Resources like reflective materials can also help maximize the light amount your plants receive. Mylar is an excellent reflective material that you can set in your cannabis grow room for improved light absorption. 

Consider investing in additional lighting systems with specialized timers for your convenience. 

  1. Check the Temperature

Temperature is also crucial when managing a grow house. Excessive and low temperatures will cause plant complications like heat stress or a light burn. The best temperature for cannabis plants averages between 70-86°F (21-28°C). 

It is ideal for producing high bud yields, and ensuring your plants thrive throughout their growth. 

Using too low temperatures can lead to the cannabis leaves canoeing issue. Extreme temperatures also cause plant stress, leading to various secondary health complications. 

Resources like thermometers will help regulate the yield of cannabis plants. Remember to also invest in fans, humidifiers, and air conditioners for the best results.

  1. Check the Humidity

Humidity is also crucial in maintaining your cannabis plant’s growth. The best humidity levels of cannabis plants average between 40-60%, related to various plant health conditions. 

Low humidity levels can lead to issues like stunted growth and plant stress complications. Excessive humidity levels cause the plant to develop complications like the leaves’ canoeing complication. 

One of the best ways to fix humidity involves using a humidifier with customized settings. Maintaining the correct air circulation levels is also crucial for the functionality of the grow house. Resources like fans are perfect for the air circulation process.
