T-One Cal+Mag 1L

T-ONE CALMAG PRO is a professional liquid fertilizer developed to maintain optimal nutritional balance in high-performance indoor crops. It is specifically formulated to prevent and correct calcium, magnesium, and iron deficiencies, commonly found in intensive systems under artificial lighting, where rapid growth requires precise and consistent nutrition. It is a nitrogen-based solution with micronutrients, highly soluble and readily available to plants.

Its guaranteed composition provides 3.0% total nitrogen, distributed as 2.75% nitrate nitrogen and 0.25% ammoniacal nitrogen, ensuring balanced and continuous uptake. It also supplies 3.25% soluble calcium (CaO), essential for strong cell wall formation, healthy root development, and proper cell division, helping to prevent deformations, leaf-edge necrosis, and growth lockouts typical in indoor cultivation.

The soluble magnesium (MgO 1.25%), a core component of chlorophyll, supports efficient photosynthesis and active plant metabolism. It plays a key role in protein synthesis, enzymatic activity, and energy redistribution, directly influencing flower and fruit weight, quality, and uniformity.

The formula is completed with water-soluble iron (Fe 0.10%) chelated with EDTA, ensuring availability even under unfavorable pH conditions or hard water. Iron is essential for chlorophyll synthesis and for preventing chlorosis in young leaves, one of the most common issues in indoor crops.
