Coco is not an inert medium in the way clay or rockwool are — it holds a cation exchange capacity that actively grabs \u003cstrong\u003ecalcium and magnesium\u003c\/strong\u003e out of the feed and releases potassium in their place, which is why a general-purpose nutrient run in coco produces deficiencies that look like a pH fault. COCOGROW is formulated around that behaviour rather than in spite of it. It is supplied as a \u003cstrong\u003etwo-part A and B\u003c\/strong\u003e because the calcium in one half and the sulphates and phosphates in the other will precipitate out if they are ever concentrated together.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormulated for coco specifically\u003c\/strong\u003e — the calcium and magnesium levels account for what the medium takes out, so a separate Cal-Mag is often unnecessary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-part for stability\u003c\/strong\u003e — A and B stay separate so nothing precipitates in the bottle or the tank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVegetative ratios\u003c\/strong\u003e — nitrogen-led for leaf and stem, with the balance to build the frame the flowering stage will load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePairs directly with COCOBLOOM\u003c\/strong\u003e — the same system, switched at the flip, so there is no change of brand mid-cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree sizes\u003c\/strong\u003e — from a single tent up to a room running a bulk reservoir\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCoco Strips Calcium Out of an Ordinary Feed\u003c\/h3\u003e\u003cp\u003eThe classic coco failure is a grower using a soil or hydro nutrient and watching the plant develop \u003cstrong\u003einterveinal yellowing and weak roots\u003c\/strong\u003e within a fortnight. It reads like a lockout and gets treated with a pH adjustment that does not help, because the actual cause is the medium exchanging its own potassium for the calcium and magnesium in the feed. A coco-specific base carries those elements at a level that accounts for the exchange, so what the plant is offered is what it actually receives — which is the difference between \u003cstrong\u003epoor nutrient uptake\u003c\/strong\u003e and steady growth.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlways add A first, then B\u003c\/strong\u003e — into water, never to each other, and stir between the two\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEqual parts:\u003c\/strong\u003e A and B go in at the same rate as one another\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoco, vegetative stage:\u003c\/strong\u003e follow the Hy-Gen feed chart for the strength, building up as the plant establishes rather than starting at full\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH:\u003c\/strong\u003e hold \u003cstrong\u003e5.8–6.2\u003c\/strong\u003e in coco, and check it after the feed is fully mixed rather than partway\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch to COCOBLOOM\u003c\/strong\u003e when the plant moves into flower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNever store mixed\u003c\/strong\u003e — make up what a reservoir needs and no more\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 two-part base nutrient, A and B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium:\u003c\/strong\u003e cocopeat and coco blends\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStage:\u003c\/strong\u003e vegetative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixing:\u003c\/strong\u003e A first, then B, both into water and never combined neat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget pH in coco:\u003c\/strong\u003e 5.8–6.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePartner product:\u003c\/strong\u003e COCOBLOOM A\u0026amp;B for the flowering stage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Hy-Gen","offers":[{"title":"1L","offer_id":53621306982666,"sku":"NUT-HYGE-002-01","price":29.9,"currency_code":"GBP","in_stock":true},{"title":"5L","offer_id":53621318058250,"sku":"NUT-HYGE-002-02","price":83.49,"currency_code":"GBP","in_stock":true},{"title":"20L","offer_id":53621318091018,"sku":"NUT-HYGE-002-03","price":277.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/hy-gen-cocogrow-ab-1l-1.png?v=1788432554","url":"https:\/\/hydrocropshop.co.uk\/products\/hy-gen-cocogrow-ab","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
