SHOGUN SAMURAI HYDRO BLOOM FOR SOFT WATER

Description

SHOGUN Samurai Hydro Bloom for Soft Water is a professional two-part flowering base nutrient formulated for hydroponic systems using soft or RO-purified water that we have been recommending to UK growers since 2017. Building on the same soft-water nutritional philosophy as Samurai Hydro Grow Soft Water, this bloom variant delivers the elevated phosphorus and potassium profile that flowering plants demand while simultaneously providing enhanced calcium and magnesium fractions to compensate for the absence of these elements in soft and RO-treated water. The result is a complete, balanced flowering nutrition programme that works reliably regardless of source water quality.

Flowering Nutrition in Soft Water: Why Standard Nutrients Fall Short

During flowering, phosphorus and potassium demands increase substantially — and so does calcium demand, particularly for cell wall formation in rapidly expanding flower tissue. A grower using standard hard-water hydroponic nutrients with RO water will typically see calcium deficiencies develop in mid-flower precisely when calcium demand is highest and background supply from tap water is zero. The necrotic leaf tips, blossom end rot and structurally weak flower tissue that result are entirely preventable with the right nutrient formulation. Samurai Hydro Bloom Soft Water builds a complete mineral supply from the ground up, with elevated calcium as a core component of the A part and appropriately elevated magnesium in the B part — no separate CalMag supplementation required at standard dosage rates for most soft-water growing conditions.

Mixing Protocol and Bloom Programme

Mix Part A and Part B at equal volumes in RO or soft water — typically 2–5 ml per litre of each depending on growth stage — diluting each separately before combining. Target EC 1.4–2.2 mS/cm during peak flower. Maintain pH 5.8–6.2. For additional bloom support, pair with SHOGUN PK Warrior 9/18 from week 4 of flowering, SHOGUN Sumo Active Boost throughout, and SHOGUN Dragon Force as a finishing product in the final 1–2 weeks before flush.
