THE PRODUCT

The micronutrients your plants are quietly missing.

Magnesium powers chlorophyll. Iron drives photosynthesis. Boron, zinc, manganese — the 'little' nutrients that bottleneck growth when they're missing. Most fertilizer programs ignore them entirely.

Vitamin Sea is a kelp-derived micronutrient complex. Bioavailable Mg in chelated form. Trace minerals from oceanic kelp at concentrations plants actually need. The corrective input that makes the rest of your program work.

Why no NPK?

Vitamin Sea isn't a macro-nutrient fertilizer — it's a concentrated micronutrient supplement. Magnesium (2.9%) plus iron, manganese, zinc, boron, and a full spectrum of trace elements measured in parts per million, not percent.

Plants need very little of these. But they break without them — yellowing leaves, stunted growth, poor fruit set.

NPK feeds the engine. Vitamin Sea oils the gears.

APPLICATION

How to Use

1

Mix ¼ tsp per gallon

Apply every 2–3 waterings or weekly as a supplement.

2

Best as foliar feed

Micronutrients absorb quickly through leaf tissue. Spray at lights-off.

3

Use throughout the cycle

Demand is highest during flower, but plants benefit from veg through harvest.

FAQ

Product Questions

How do I know if I need it?

Yellowing between leaf veins (interveinal chlorosis) usually means Mg deficiency. New growth pale = micronutrient deficit. Vitamin Sea fixes both.

Can I use it with cal-mag products?

Yes. Vitamin Sea covers the Mg + micros. King Krustacean covers calcium. They stack cleanly.

Foliar or soil?

Foliar for fast correction. Soil for steady supplementation. Both work.

Does it replace a base fertilizer?

No — Vitamin Sea is supplementary. Run with Veg or Bloom for the foundation.
