General Hydroponics CaliMagic Calcium Magnesium Supplement – 55 Gallon Bulk Drum

General Hydroponics CaliMagic calcium magnesium supplement (1-0-0) is a concentrated, fully soluble Cal-Mag formula engineered to prevent secondary nutrient deficiencies in fast-growing plants. Ideal for commercial operations running reverse osmosis water, coconut coir, or prepared soilless mixes, this 55-gallon bulk drum delivers consistent calcium and magnesium support at production scale.

Prevents Deficiencies, Protects Crop Quality

This CaliMagic calcium magnesium supplement helps prevent blossom end rot and tip burn in calcium-intensive crops like tomatoes and lettuce. Its clean, fully soluble formula will not clog spray lines or drip emitters and is safe for use in reservoirs — compatible with most fertilizer programs without risk of precipitation or blockage.

  • Reverse Osmosis or Purified Water: Add 1 tsp per gallon before adding nutrient solution
