The symptoms look like a feed problem, so growers push EC, the plants take up even less, growth slows and flowers finish airy and light. Correcting downward into the 5.5 to 6.5 window keeps the solution available at the root, so the bloom feed you are already running does its job and yields hold up.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrder of mixing:\u003c\/strong\u003e add and stir all nutrients first, then adjust pH last\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget range:\u003c\/strong\u003e \u003cstrong\u003epH 5.5 to 6.5\u003c\/strong\u003e, measured with a calibrated meter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e add small amounts at a time, mix thoroughly and let the solution stabilise before retesting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil:\u003c\/strong\u003e aim towards the upper end of the range and retest after each top-up\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoco and hydro:\u003c\/strong\u003e work towards the lower end and check the tank daily as plants drink\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNever\u003c\/strong\u003e add concentrated products directly together\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Dutch Pro\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Concentrated pH adjuster (downward correction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBase:\u003c\/strong\u003e Phosphorus based\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended pH range:\u003c\/strong\u003e 5.5 - 6.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage:\u003c\/strong\u003e Later plant development \/ flowering\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable media:\u003c\/strong\u003e Soil, coco and hydroponic systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Added gradually to a fully mixed nutrient solution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRange:\u003c\/strong\u003e Available in multiple working sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Dutch Pro","offers":[{"title":"1L","offer_id":53445766447370,"sku":null,"price":9.49,"currency_code":"GBP","in_stock":true},{"title":"5L","offer_id":53445766480138,"sku":null,"price":37.49,"currency_code":"GBP","in_stock":true},{"title":"10L","offer_id":53445766512906,"sku":null,"price":51.49,"currency_code":"GBP","in_stock":true},{"title":"20L","offer_id":53445766545674,"sku":null,"price":95.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/PhBloom-B.png?v=1785293083","url":"https:\/\/hydrocropshop.co.uk\/products\/dutch-pro-ph-down-bloom","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
