Calcium and magnesium deficiencies are among the most common lockout issues in fast-growing, high-EC feeding programmes, particularly in coco and RO-fed hydro systems where the source water carries little of either mineral naturally.\u003c\/p\u003e\u003cp\u003eBecause it is a straight two-element product, growers can dose it independently of the base feed to correct a deficiency precisely rather than switching an entire feed line to chase one issue.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15% calcium, 3% magnesium\u003c\/strong\u003e, fully water-soluble\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrects cal-mag deficiencies\u003c\/strong\u003e common in coco and RO-fed systems\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSourced from calcium nitrate and magnesium sulfate\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDoses independently of the main base feed\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSuits soil, coco and hydroponic systems\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAdd to the reservoir at every feed where the base or source water runs low in calcium or magnesium\u003c\/li\u003e\n\u003cli\u003eDissolve fully before combining with other nutrients\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\u003eGuaranteed analysis:\u003c\/strong\u003e 15% Calcium, 3% Magnesium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSource:\u003c\/strong\u003e calcium nitrate, magnesium sulfate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e soluble powder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"RAW","offers":[{"title":"2oz","offer_id":53500719169802,"sku":"NUT-RAW1-003-01","price":12.58,"currency_code":"GBP","in_stock":true},{"title":"2lb","offer_id":53500719202570,"sku":"NUT-RAW1-003-02","price":89.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/calmag_MainImage_02527059-64d6-49b3-b8ff-fb3ce8e25626.jpg?v=1786377604","url":"https:\/\/hydrocropshop.co.uk\/products\/raw-calcium-magnesium","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
