That is not a shortage of base nutrients but of calcium and magnesium, and it soon becomes poor nutrient uptake because the plant cannot build tissue fast enough to use what you give it. Correcting the base water keeps uptake even and leaves dark.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoil and light mix:\u003c\/strong\u003e add Calmag to plain water at the rate given on the label before anything else goes in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoco:\u003c\/strong\u003e use with every feed where you are starting from RO or soft water, so the medium is never running short.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixing order:\u003c\/strong\u003e Calmag into the water first, stir well, then add your base feed and boosters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003epH:\u003c\/strong\u003e check and adjust only once the full solution is mixed, then water your plants directly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage:\u003c\/strong\u003e keep sealed, cool and out of direct sunlight, and shake before use.\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 Concentrated organic calcium and magnesium supplement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e Calcium and magnesium blend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater types:\u003c\/strong\u003e Hard water, soft water and reverse osmosis water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e Soil and coco grows, hobby and professional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosage:\u003c\/strong\u003e As stated on the product label\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BioBizz","offers":[{"title":"250ml","offer_id":53445687673098,"sku":null,"price":4.49,"currency_code":"GBP","in_stock":true},{"title":"500ml","offer_id":53445687705866,"sku":null,"price":8.95,"currency_code":"GBP","in_stock":true},{"title":"1L","offer_id":53445687738634,"sku":null,"price":10.49,"currency_code":"GBP","in_stock":true},{"title":"5L","offer_id":53445687771402,"sku":null,"price":71.49,"currency_code":"GBP","in_stock":true},{"title":"10L","offer_id":53445687804170,"sku":null,"price":89.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/Biobizz-Calmag-G.jpg?v=1785289639","url":"https:\/\/hydrocropshop.co.uk\/products\/biobizz-calmag","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
