CES Amplified Cal-Mag

CES Amplified Cal-Mag by Cutting Edge Solutions is a liquid calcium and magnesium supplement formulated for growers who need to correct or prevent deficiencies in soil, coco coir, and hydroponic systems. It delivers pure, rapidly absorbable forms of both nutrients, making it a practical addition to any nutrient program where calcium and magnesium levels need support.

Why Choose CES Amplified Cal-Mag

Calcium and magnesium deficiencies are among the most common problems growers encounter, particularly in coco coir and soft-water environments. CES Amplified Cal-Mag addresses this with a concentrated liquid formula that delivers these minerals in pure, rapidly absorbable forms, so plants can take them up quickly without waiting for a slow-release breakdown process.

• Pure, rapidly absorbable calcium and magnesium. The formulation is designed for fast uptake, making it useful when deficiency symptoms appear and a quick correction is needed.
• Coco coir buffering. Coco coir is naturally high in potassium and sodium, which can compete with calcium at uptake sites. Adding Cal-Mag Amplified before and during coco grows helps pre-saturate the cation exchange sites, reducing the risk of calcium lockout once plants are in the media.
• Maximizes cation exchange capacity. By supplying additional calcium, the supplement helps maintain a healthy balance of cations in the root zone, which supports overall nutrient uptake efficiency.
• Supports magnesium-demanding varieties. Some plant varieties and heirlooms have higher magnesium requirements than standard formulas provide. Cal-Mag Amplified allows growers to dial in elevated magnesium levels without reformulating their entire feed program.
• Broad media compatibility. Works as a supplement in native soil, soilless mixes, coco coir, and recirculating or drain-to-waste hydroponic systems.

Best Uses for CES Amplified Cal-Mag

This supplement is most useful in situations where calcium and magnesium supply is insufficient from base nutrients alone or from the growing media. The following use cases are drawn directly from the product description.

• Native soil supplementation. Soil growers working with mixes that are light in calcium and magnesium can use Cal-Mag Amplified to fill those gaps without switching base nutrients.
• Coco coir grows — buffering phase. Before first use or transplant, flushing coco with a Cal-Mag solution saturates cation exchange sites and prevents early-stage calcium deficiency once plants are introduced.
• Coco coir grows — maintenance phase. Because coco continues to release potassium and bind calcium throughout the grow, maintaining a steady cal-mag dose in every watering helps keep the cation balance stable.
• Heirloom and specialty varieties. Certain cultivars have elevated magnesium demands relative to what standard 3-part or 2-part nutrient programs supply. Cal-Mag Amplified lets you raise magnesium independently without adjusting NPK ratios.
• Soft-water or RO-water systems. Reverse osmosis and very soft tap water strips out background calcium and magnesium. Running Cal-Mag Amplified brings the baseline mineral content back up before nutrient additions, improving pH stability and nutrient solubility.
• Correcting visible deficiency symptoms. If plants show interveinal chlorosis (magnesium deficiency) or tip burn and blossom-end rot (calcium deficiency), a short-term elevated dose can help reverse early symptoms while you adjust the broader feed program.

If you are running CES Amplified Cal-Mag alongside a pH management routine, pairing it with a reliable pH-balanced base nutrient can simplify the overall program.

Dosing Guidelines

The canonical product data does not include a specific ml-per-gallon dose rate for this SKU. The following guidelines reflect standard practice for liquid cal-mag supplements of this type; consult the label on your specific bottle for the manufacturer’s recommended rate.

• Start low, adjust up. Begin at a conservative dose (typically 1–2 ml per gallon) and increase based on plant response and runoff EC readings.
• Add to water first. When mixing a nutrient solution, add Cal-Mag Amplified to plain water before adding base nutrients. This prevents precipitation and ensures even distribution.
• Coco pre-soak. For new coco coir, pre-soak the media with a dilute cal-mag solution (at target pH 5.8–6.2) before introducing plants. This buffers the media and reduces the risk of early calcium lockout.
• pH range. Calcium and magnesium availability peaks between pH 6.0–7.0 in soil and 5.8–6.5 in coco and hydro. Check and adjust your solution pH after adding cal-mag, not before.
• EC monitoring. Track your overall EC as you add supplements. Cal-Mag contributes to total dissolved solids, so factor it into your target EC range for each growth stage.
• Foliar application. For a rapid response to visible deficiency, a dilute foliar spray (approximately 1 ml per litre) applied in low-light conditions can speed correction. Avoid spraying in direct light to prevent leaf burn.

For grow environment setup, a well-ventilated grow tent also helps maintain stable temperatures that support calcium and magnesium uptake — both nutrients are less mobile in cold root zones.
