{"product_id":"med-tek-cal-mag-micro","title":"Med-Tek Cal Mag Micro","description":"\u003cp\u003eWhen the base feed or the water supply leaves a plant short, the gap usually comes down to calcium, magnesium and the trace elements that travel with them. Med-Tek Cal Mag Micro is a concentrated supplement made to fill that gap, blending readily available calcium and magnesium with a full spectrum of micronutrients. One addition can correct a deficiency that's already appeared. It can also carry plants through periods of high nutrient demand, when growth is fast and the feed is working hardest. Med-Tek say it quickly corrects deficiencies and boosts plant performance through those stretches. The real strength is the combination! You don't have to chase calcium, magnesium and trace elements with separate bottles, because the whole group arrives together in a form plants can take up easily.\u003c\/p\u003e\u003cp\u003eCalcium and magnesium carry most of the load in Cal Mag Micro. Its calcium is built into cell walls, and once it's in place it barely moves around the plant. That's why a calcium shortage tends to show first in new growth. Its magnesium is the atom every chlorophyll molecule is built around. Without enough of it, a plant can't make the green pigment it needs to capture light for photosynthesis.\u003c\/p\u003e\u003cp\u003eAlongside those two, Cal Mag Micro carries iron, manganese, zinc, copper, boron and molybdenum. These trace elements drive the enzymes and growth processes behind healthy leaves and strong development. The iron, manganese, zinc and copper are chelated, meaning each one is bound to an organic molecule that keeps it dissolved and available. That way it doesn't drop out of solution or lock up before the roots can reach it. A small amount of potassium completes the formula.\u003c\/p\u003e\u003cp\u003eSoft water is where Cal Mag Micro really earns its place. Rainwater and reverse osmosis water carry little calcium or magnesium of their own. A feed made with them can run short even when the base nutrient is mixed correctly. When soft water is behind the shortfall, this concentrate fixes it at the source by putting back what the water never had. The formula has no nitrogen or phosphorus. It works alongside a complete base nutrient and isn't a feed on its own.\u003c\/p\u003e\u003cp\u003eMed-Tek Nutrients is based in Smithfield, South Australia, and the same Cal Mag Micro concentrate goes into all 3 pack sizes.\u003c\/p\u003e","brand":"MED-TEK","offers":[{"title":"1 L","offer_id":67551606964382,"sku":"PLACEHOLDER910179","price":42.5,"currency_code":"AUD","in_stock":false},{"title":"5 L","offer_id":67551606997150,"sku":"PLACEHOLDER910180","price":159.99,"currency_code":"AUD","in_stock":false},{"title":"20 L","offer_id":67551607029918,"sku":"PLACEHOLDER910181","price":479.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/Med-Tek_Cal-Mag_Micro_1L.png?v=1792938299","url":"https:\/\/www.hydrooasis.com.au\/products\/med-tek-cal-mag-micro","provider":"Hydro Oasis","version":"1.0","type":"link"}
