That happens most in hard vegetative growth, in a heavily populated room, and in recirculating systems where the solution drifts as it is used. It exists so that the fix is a measured top-up rather than dumping and remaking a reservoir — which is the expensive and disruptive alternative, and the one most growers reach for by default.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTargets the two elements that go first\u003c\/strong\u003e — nitrogen for leaf and stem, potassium for water regulation and transport\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjusts a live reservoir\u003c\/strong\u003e — correct a drifting tank without tipping it away and starting again\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUseful in recirculating systems\u003c\/strong\u003e, where the ratio moves as the plant draws unevenly on the solution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports heavy vegetative growth\u003c\/strong\u003e, where a general base is often the limiting factor rather than the light\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo bulk sizes\u003c\/strong\u003e — sized for rooms rather than single tents\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePale, Stalling Growth in a Tank That Reads Right\u003c\/h3\u003e\u003cp\u003eA recirculating reservoir does not empty evenly. Plants take water and individual elements at different rates, so a tank mixed correctly on Monday can be short of nitrogen by Thursday while its EC still reads close to target — the total is right, the balance is not. What shows is \u003cstrong\u003eslow growth\u003c\/strong\u003e, older leaves yellowing from the bottom up, and a plant that stops filling out despite a feed that looks correct on the meter. A targeted top-up restores the ratio in place, which is faster and cheaper than a full change and far better than feeding harder across the board.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagnose first:\u003c\/strong\u003e lower-leaf yellowing that climbs the plant is the nitrogen signature — do not dose on suspicion alone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVegetative stage:\u003c\/strong\u003e the main use, alongside the base feed rather than instead of it\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecirculating tanks:\u003c\/strong\u003e add to the reservoir, circulate fully, then re-read\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlways re-check EC and pH\u003c\/strong\u003e after dosing — this raises both\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGo up in steps:\u003c\/strong\u003e a small correction re-read the next day beats a large one you cannot take back out\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEase off into flower\u003c\/strong\u003e, where nitrogen demand falls away\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\u003eType:\u003c\/strong\u003e nitrogen and potassium supplement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurpose:\u003c\/strong\u003e correcting an N and K shortfall in a live reservoir\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage:\u003c\/strong\u003e primarily vegetative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia:\u003c\/strong\u003e all systems, most useful in recirculating hydroponics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEC and pH:\u003c\/strong\u003e both raised — re-check and correct after dosing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Hy-Gen","offers":[{"title":"5L","offer_id":53621331132682,"sku":"NUT-HYGE-009-01","price":94.49,"currency_code":"GBP","in_stock":true},{"title":"20L","offer_id":53621333164298,"sku":"NUT-HYGE-009-02","price":332.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/hy-gen-nitro-k-5l-1.png?v=1788432600","url":"https:\/\/hydrocropshop.co.uk\/products\/hy-gen-nitro-k","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
