Is Ocean-K a complete fertilizer?

No. At 2-2-18 it is low in nitrogen and phosphorus and very high in potassium. Use it alongside a nitrogen and phosphorus source, especially during vegetative growth.

Can I use it in hydroponics?

Yes. It is fully water-soluble and marketed for hydroponic reservoirs, drip irrigation and fertigation. Mix it thoroughly and watch fine emitters for residue.

When should I feed it?

The high potassium ratio suits flowering and fruit development. The maker also says it helps plants through heat, drought and transplant stress.

Can I spray it on leaves?

Yes, it is labeled for foliar sprays as well as soil drenches and reservoir feeding. Follow the label rate for foliar use.

Our take on the Boca Hydro Ocean-K 2-2-18 Water-Soluble Kelp Fertilizer

Ocean-K 2-2-18 is a water-soluble kelp fertilizer built around a high-potassium ratio, aimed at flowering and fruiting stages. The potassium comes with enzymatically hydrolyzed Ascophyllum nodosum kelp and humic acid, which the maker says improves soil structure and nutrient uptake. The 2-2-18 analysis is low in nitrogen and phosphorus, so it fits bloom boosters and ripening crops rather than general vegetative feeding. It dissolves fully for soil, coco, foliar sprays, drenches, drip lines and hydroponic reservoirs.
