Its 0-31-21 ratio delivers a concentrated hit of potassium and phosphorus exactly when a plant is putting the most energy into bud development, with kieserite adding fast-acting magnesium and sulphur alongside amino acids that help the plant actually use what it's being fed.\u003c\/p\u003e\u003cp\u003eIt's used across the final three weeks before harvest, in hydro, coco or soil, layered on top of whatever base nutrient is already running — one measure per 100 litres in week six, stepping up to two measures per 100 litres for weeks seven through nine. Growers reach for it when bud development starts to plateau, or when they simply want to push for more flower size, weight and potency in the finishing weeks. It's not recommended for drip-feed systems, where the powder format is harder to keep in solution.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-strength 0-31-21 PK ratio\u003c\/strong\u003e for late-stage flowering\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eKieserite adds fast-acting magnesium and sulphur\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eAmino acids aid nutrient uptake\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBoosts flower size, weight and potency\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple staged dosing\u003c\/strong\u003e across the final three weeks\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eLayers onto your existing base feed\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eNPK: 0-31-21 + Mg\u003c\/li\u003e\n\u003cli\u003eContains: potassium, phosphorus, kieserite, vitamin B2, amino acids, microelements\u003c\/li\u003e\n\u003cli\u003eDose: week 6 — 1 measure\/100L; weeks 7-9 — 2 measures\/100L\u003c\/li\u003e\n\u003cli\u003eNot recommended for drip-feed systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"BioGreen","offers":[{"title":"Box of 6 (450g)","offer_id":53500712812810,"sku":"biogreen-flower-boost-450g","price":26.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/LondonGrow_Nutrients_Biogreen_FlowerBoost.png?v=1786377513","url":"https:\/\/hydrocropshop.co.uk\/products\/biogreen-flower-boost","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
