The importance of copper for cannabis plants 

If you’re serious about cultivating top-notch cannabis, you can’t ignore the copper factor. This essential micronutrient plays a crucial role in the growth and development of marijuana seeds, contributing to processes like chlorophyll synthesis, cell wall formation, photosynthesis, and disease resistance. Let’s dive deep into the importance of copper in cannabis plants.

Benefits of copper for cannabis plants:

Copper for plants is formed of enzymes and proteins, rocking the world of photosynthesis and metabolism. It’s not just about structure; it’s about enhancing flavor, color, and overall plant health. Here’s the lowdown on the perks:

• Intensifies bud flavor and color: Thanks to its role in chlorophyll production, copper adds that vibrant green to your leaves and boosts the taste of your beloved buds.
• Acts as a preventive fungicide: Copper’s antifungal properties make it a superhero in preventing harmful fungi and bacteria from crashing your cultivation party.
• Boosts growth and plant health: Essential for protein and enzyme production, copper is your go-to for promoting robust growth and overall plant wellness.
• Regulates cannabis growth: Keeping things in check, copper stimulates the development of new leaves and shoots, ensuring your plants reach their full potential.

How much copper does your cannabis need?

Marijuana plants are not copper gluttons, but a deficiency can mess with their ability to turn light into energy for flower production. Check out the copper dosage cheat sheet:

Remember, these amounts can vary based on factors like soil type, water quality, and sunlight exposure. Stay vigilant and adjust as needed for a copper-rich cannabis journey.

Symptoms of copper deficiency in marijuana

Spotting copper deficiency is rare but crucial. Watch out for signs like darkening with blue or purple hues, bright yellow or white edges on leaves, metallic sheen, stunted growth, and smaller, lower-quality flowers during flowering.

• The plants become darker, with hints of blue or purple.
• On the other hand, the darker they become, a bright yellow or white color develops at the edges of the leaves.
• The leaves may take on a more metallic and shiny appearance. On certain occasions, they may curl downward.
• Growth slows down, resulting in smaller-than-normal leaves.
• If in bloom, it affects their growth, causing the flowers to be smaller and of poorer quality.

Preventing Copper Deficiency

Keep your pH in check! For soil, aim for pH 6-7 and for hydroponics, stay in the 5.5-6.5 range. Deliver the right mineral mix to avoid excess iron, aluminum, and manganese.

How to solve copper deficiency in plants?

Copper deficiency in plants is often attributed to a pH imbalance in the plant root zone, hindering proper nutrient absorption, or excessive watering that depletes soil micronutrients. To rectify this, the following steps can be taken:

Root Flush

One of the primary pH imbalances is caused by the accumulation of salts and minerals in the soil. Once the substrate is flushed, the appropriate nutrient ratio can be added to restore health to the root zone.

Other Options for Treating Copper Deficiency:

At times, it may be necessary to introduce copper through fertilizers or fungicides containing it, such as Auto Boom. These products are readily available online. Alternatively, green sand, kelp, or compost can be used.

If these are not available, coins like 1, 2, or 5-cent coins can be immersed in water overnight and used if needed.

Excessive copper in cannabis plants

As with any other nutrient, an excess of copper can be detrimental to plants. However, the risk of nutrient excess is minimized when using commercial fertilizers. Symptoms of excess copper in plants include:

• Damaged roots leading to weaker and sicker plants.
• Slower plant growth.
• Reduced branching development.
• Brown or black spots on leaves, starting at the edges and spreading to the center.
• Decreased flowering and fruit quality.

Excessive copper can antagonize interactions with other nutrients such as iron, manganese, zinc, boron, molybdenum, and chlorine, potentially causing deficiencies in these compounds. The excess is primarily influenced by the plant species and soil conditions.

How to Avoid Excessive Copper?

Firstly, check the substrate’s Electrical Conductivity (EC) when watering by collecting and testing the runoff water. To correct it, perform a root flush and lightly fertilize. Additionally, always follow the manufacturer’s instructions for use. By adhering to these steps, one can achieve a cultivation with an adequate copper supply for plants, resulting in high-quality yields with enhanced flavor.
