Calmag – Calcium & Magnesium 1 Liter | Prevents & Corrects Deficiencies<\/h1>\n

Calmag 1L<\/strong> is a highly concentrated calcium and magnesium supplement<\/em> for plants in soil, hydroponics and coco<\/strong>. Calcium (Ca) is a structural building block of cell walls<\/strong> and provides strength; magnesium (Mg) forms the core of chlorophyll<\/strong>, the green leaf pigment that captures light energy for photosynthesis<\/strong> and the production of sugars. With Calmag you prevent and correct Ca\/Mg deficiencies so that plants grow vigorously<\/strong> and reach their maximum potential.<\/p>\n

Why Calmag?<\/h2>\n

Deficiencies in calcium or magnesium lead to chlorosis (yellowing), weak cell structures and inhibited growth. Calmag<\/strong> rapidly replenishes Ca\/Mg, supports chlorophyll production and increases energy levels. The result is deep green leaf color<\/strong>, strong stems and stable development in both growth and flowering.<\/p>\n

Key benefits<\/h2>\n
    \n
  • Eliminates calcium deficiencies<\/strong> and magnesium deficiencies<\/strong>.<\/li>\n
  • Increases energy production<\/strong> via enhanced photosynthesis (more chlorophyll).<\/li>\n
  • Compatible with all substrates<\/strong>: soil\/soil, hydro and coco.<\/li>\n
  • Highly concentrated<\/strong> for accurate, low dosing.<\/li>\n
  • NPK:<\/strong> 0.1 – 0.1 – 0.1 (slight NPK contribution, no interference with your schedule).<\/li>\n<\/ul>\n

    When do you use Calmag?<\/h2>\n

    Use weekly from week 1 of the growth phase<\/strong> or as soon as symptoms of Ca\/Mg deficiency become apparent. Calmag is particularly useful when growing with extra CO\u2082.<\/strong> Important:<\/em> Use Calmag when growing with elevated CO\u2082 levels (manufacturer’s advice: only with extra CO\u2082; with high CO\u2082 levels, the Ca\/Mg requirement is extra high). Match this to your growing schedule.<\/p>\n

    Dosage & application<\/h2>\n
      \n
    • Dosage in general:<\/strong> 0.1 – 1.0 ml per 1 L of water.<\/li>\n
    • Frequency:<\/strong> apply weekly (start in week 1 of growth).<\/li>\n
    • Instructions for use:<\/strong> shake<\/strong> well before use<\/strong>; store cool, dark and sealed<\/strong> in original container<\/strong>; keep out of reach of children.<\/li>\n<\/ul>\n

      For whom is 1 liter ideal?<\/h2>\n

      The 1L package<\/strong> is perfect for hobby growers or smaller setups that want accurate adjustments<\/strong> without large supplies. Suitable for soft water, coco growing and situations where you need occasional Ca\/Mg supplementation.<\/p>\n

      Availability:<\/strong> Calmag is available in 1L, 5L, 10L and 20L. Please note that some packaging may vary by country.<\/p>\n<\/section>\n","protected":false},"excerpt":{"rendered":"
