Fox Farm BushDoctor Cal-Mag — OMRI Listed Calcium & Magnesium

BushDoctor Cal-Mag is an OMRI Listed organic calcium and magnesium supplement. Essential for preventing blossom end rot, tip burn, and interveinal chlorosis — the most common deficiencies in container-grown plants.

• OMRI Listed — certified for organic production
• Calcium + Magnesium — addresses the two most common secondary deficiencies
• Prevents blossom end rot — critical for tomatoes, peppers, and fruiting plants
• Corrects interveinal chlorosis — magnesium deficiency shows as yellowing between veins
• Essential for RO water and coco coir — both strip calcium and magnesium

Use as a supplement alongside any organic base nutrient program. Especially important when using reverse osmosis water or coco-based media.
