EHG Cal Mag Plus

EHG Cal Mag PLUS is an essential addition to the core EHG mineral plant nutrient feeding ranges, acting as a reliable solution when you detect symptoms of calcium or magnesium deficiencies in your plants. To gain further expertise, make sure to delve into EHG's all-encompassing grow guide for advanced insights. When applying it for root feeding, adhere to the recommended dosage of 2ml per liter. Additionally, EHG Cal Mag PLUS proves highly effective in buffering coco coir. This involves soaking a 5kg coir brick in 200ml of the solution for several hours, followed by rinsing with clean water.

Key Contents:

• Nitrogen (N): 4%
• Calcium (Ca): 3.2%
• Magnesium (Mg): 1.2%
• Iron (Fe): 0.1%

Buffering Coco Coir:

Buffering coco coir involves a process that replaces the potassium and sodium initially held by the coir with added calcium and magnesium. By performing this process before introducing plants, it ensures that the coir doesn't compete with nutrient solutions for calcium and magnesium, thus preventing nutrient theft by improperly buffered and rinsed coir.

Common Reasons for Calcium and Magnesium Deficiencies:

• Imbalanced pH Levels: Incorrect pH levels in the growing medium can lead to nutrient lockout. Both high and low pH levels can hinder calcium and magnesium uptake.

• Excessive Nutrient Levels: Elevated concentrations of other nutrients, like potassium or ammonium, can outcompete calcium and magnesium, leading to imbalances in nutrient absorption.

• Presence of Other Cations: Certain elements in the soil or growing medium, such as aluminum or iron, can form complexes with calcium and magnesium ions, rendering them unavailable to plants.

• Overfertilization: Applying excessive amounts of fertilizers, especially those rich in phosphorus, can disrupt nutrient uptake and result in calcium and magnesium lockout.

• Water Quality: Poor-quality irrigation water with high bicarbonate or carbonate levels can cause calcium and magnesium to precipitate and become less available for plant uptake.

• Competition between Nutrients: Nutrients might have antagonistic relationships, meaning an excess of one nutrient can inhibit the uptake of another, leading to nutrient lockout.

• Environmental Stress: Factors like extreme temperatures or waterlogged conditions can affect nutrient uptake and contribute to calcium and magnesium deficiencies.

Addressing calcium and magnesium deficiencies is crucial for maintaining healthy plant growth and ensuring optimal nutrient uptake, ultimately resulting in more robust and productive plant life.
