Organic Magnesium & Micronutrient Supplement for Complete Plant Nutrition
Vitamin Sea is Growganica's organic magnesium for plants — a concentrated micronutrient supplement derived from ocean minerals that delivers magnesium, iron, manganese, zinc, boron, and a full spectrum of trace elements your plants need but rarely get. If your plants show yellowing leaves, stunted growth, or poor fruit development, chances are they're missing the micronutrients that Vitamin Sea provides.
Why Your Plants Need Vitamin Sea
- Magnesium for chlorophyll — Magnesium is the central atom in every chlorophyll molecule. Without it, photosynthesis stalls and leaves turn yellow between the veins — a classic magnesium deficiency symptom
- Complete micronutrient profile — Goes far beyond a simple cal-mag supplement by delivering the full spectrum of ocean-derived trace minerals that support enzymatic reactions, hormone production, and nutrient transport
- Organic Epsom salt alternative — A superior, longer-lasting organic alternative to Epsom salt that won't disrupt soil biology or create nutrient lockout
- Deficiency prevention — Proactive application prevents the micronutrient gaps that cause yellowing leaves, blossom drop, and poor fruit quality
How to Use
Mix 2–4 tablespoons per gallon of water and apply as a soil drench or foliar spray every 1–2 weeks. Vitamin Sea is especially important during heavy flowering when micronutrient demand spikes. Use alongside Bloom and Incredible Bulk for complete flowering nutrition, and always pair with Growganica Microbes to ensure maximum mineral uptake. See our feeding schedule for timing guidance.
The Missing Piece in Your Organic Garden
Most organic fertilizers focus on NPK — nitrogen, phosphorus, and potassium. But your plants need dozens of micronutrients to truly thrive. Vitamin Sea fills this gap — essential for demanding crops like tomatoes and strawberries — with a clean, ocean-sourced organic micronutrient fertilizer that complements every product in the Growganica lineup. Pair with Kelp It Real for a potassium + micronutrient stack, or add King Krustacean for calcium + magnesium coverage.
