Phosphorus supports root development, respiration and photosynthesis, while potassium drives nutrient transport around the plant through the demanding bloom stretch that follows.\u003c\/p\u003e\u003cp\u003eA base nutrient alone often can't supply the concentrated PK spike a plant needs to commit fully to flower production. Running a short, clearly defined PK 13\/14 window gives that push without holding an elevated PK level across the whole bloom cycle, which risks locking out other nutrients if left running too long.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcentrated PK spike\u003c\/strong\u003e over a defined 3-4 day window\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEncourages the shift\u003c\/strong\u003e from vegetative stretch into flower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports root development\u003c\/strong\u003e and nutrient transport\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks alongside\u003c\/strong\u003e a standard base feed\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSuited to hydro, coco and soil\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eUse period: 3-4 days at chosen flowering stage\u003c\/li\u003e\n\u003cli\u003eSuitable media: hydroponics, coco, soil\u003c\/li\u003e\n\u003cli\u003eUse alongside: a base nutrient programme\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"House \u0026 Garden","offers":[{"title":"500ml","offer_id":53500713763082,"sku":"house-garden-pk-13-14-500ml","price":7.95,"currency_code":"GBP","in_stock":true},{"title":"1L","offer_id":53500713795850,"sku":"house-garden-pk-13-14-1l","price":12.95,"currency_code":"GBP","in_stock":true},{"title":"5L","offer_id":53500713828618,"sku":"house-garden-pk-13-14-5l","price":47.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/nutrients-1l-house-garden-pk-13-14-40097208565975.jpg?v=1786377531","url":"https:\/\/hydrocropshop.co.uk\/products\/house-garden-pk-13-14","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
