THC Cal-Mag (Calcium + Magnesium Booster) is a concentrated, soluble nutrient supplement used to prevent and correct calcium and magnesium deficiencies in plants, promoting healthy growth and stronger cell structure. 

Key Features and Benefits:

• Mineral Fortification: Increases essential levels of calcium and magnesium in plants, which are vital for strong cell walls and photosynthesis.
• Prevents Deficiencies: Addresses common issues like yellowing leaves (magnesium deficiency), stunted growth, and blossom end rot in fruits like tomatoes (calcium deficiency).
• Improves Water Quality: Ideal for use with reverse osmosis, distilled, or soft water sources that naturally lack sufficient minerals, helping to raise and stabilise EC levels.
• Enhances Nutrient Uptake: Promotes overall plant health, improves nutrient translocation, and leads to enhanced fruit and flower production.
• Compatibility: THC Cal-Mag is a concentrated, fully soluble blend that won't clog drip emitters and can be combined with other fertilisers.

Application:

• General Use: Use 1 ml per 1 Litre of nutrient solution or water.
• For Coco/Soilless Mixes: Pre-buffer the substrate by adding 1 ml per Litre of water (adjusting pH to 6.0) before planting, and continue using in the nutrient solution for the first three weeks of the vegetative phase.
• For Deficiencies: In case of existing deficiency, use 1 ml per 1 Litre of nutrient solution.
• pH Maintenance: Maintain the pH level of the nutrient solution between 5.8 and 6.3 for optimal uptake.
