{"product_id":"floramax-ca-mg-fe-powder","title":"FloraMax Ca-Mg-Fe Powder","description":"\u003cp\u003eChasing a deficiency one element at a time is slow work. FloraMax Ca-Mg-Fe Powder is a concentrated deficiency corrector that puts calcium, magnesium and iron back into the feed, together with copper, manganese, zinc, molybdenum, boron and nitrogen. FloraMax call it their ultimate Cal-Mag additive. Their reasoning is that the common deficiencies growers chase come from these nine elements, never from calcium and magnesium alone.\u003c\/p\u003e\u003cp\u003eThat's why Ca-Mg-Fe carries all nine. Several of those shortages look alike on the leaf, and pale or yellowing foliage can point to nitrogen, magnesium, iron or manganese running short. A product that tops up only two nutrients leaves you guessing which one it was. Ca-Mg-Fe covers the whole group in one addition and brings the feed back into balance without you working through the elements one by one.\u003c\/p\u003e\u003cp\u003eIt's a corrector, not a constant. In both the FloraMax VegaFlora and Veg-1 programmes, Ca-Mg-Fe sits outside the regular weekly schedule as an optional additive, used only if required. It's there for when a crop shows a shortfall, not for every tank. While a deficiency is being corrected, the crop is fed more often and given generous run-off.\u003c\/p\u003e\u003cp\u003eCa-Mg-Fe comes as a dry ProPowder. You can weigh it straight into the reservoir, or dissolve it into a liquid stock concentrate first and dose from that. Dissolved, it goes a long way! A 200 g bag makes 1 L of stock, enough for about 660 L of working nutrient solution. The 1 kg and 4 kg bags scale that up to 5 L and 20 L of stock, good for roughly 3.3 kL and 13.3 kL.\u003c\/p\u003e\u003cp\u003eEvery dose of this powder is weighed, so the one piece of kit worth sorting before your first batch is a set of scales that reads to 0.1 g. A loose powder settles differently each time, which means a scoop won't hold the same weight from one fill to the next. For reservoirs from 10 L to 1,000 L, a scale with 3 kg capacity and 0.1 g resolution suits Ca-Mg-Fe.\u003c\/p\u003e\u003cp\u003eThe powders don't spread evenly through it, so the whole pre-mix belongs in a single nutrient batch, never split across several.\u003c\/p\u003e","brand":"FloraMax","offers":[{"title":"200 g","offer_id":67551606112414,"sku":"9337839003300","price":30.0,"currency_code":"AUD","in_stock":false},{"title":"1 kg","offer_id":67551606145182,"sku":"9337839003317","price":114.0,"currency_code":"AUD","in_stock":false},{"title":"4 kg","offer_id":67551606177950,"sku":"9337839003324","price":374.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/FloraMax_Ca-Mg-Fe_Powder_200g.png?v=1792940916","url":"https:\/\/www.hydrooasis.com.au\/products\/floramax-ca-mg-fe-powder","provider":"Hydro Oasis","version":"1.0","type":"link"}
