Liquid Ca, Mg & Fe correction that fits the Athena Blended program — tote-scale for commercial runs.
Athena Blended CaMg (2-0-0) is a liquid calcium, magnesium, and chelated iron supplement formulated to pair with the Athena Blended two-part system — correcting deficiencies driven by RO water, high-demand cultivars, or inert media without disrupting overall elemental balance. SKU LQB-CM-275G ships as a 275-gallon tote sized for facilities that run continuous, high-volume irrigation.
Athena Blended CaMg is a 2-0-0 liquid supplement delivering calcium, water-soluble magnesium, and chelated iron in a single bottle. It is part of the Athena Blended Line — a sediment-free, all-liquid program built around Grow A+B for vegetative stages and Bloom A+B for flowering, with CaMg used on an as-needed basis across all growth stages.
The formula is specifically engineered to correct calcium, magnesium, iron, and nitrogen shortfalls without pushing other elemental ratios out of range. Chelated iron (EDTA/EDDHA forms are used across the Athena line) stays plant-available across a wider pH window than unchelated sources. The result is targeted intervention — you dial in Ca/Mg without rebuilding your entire feed.
CaMg is most useful in three scenarios that are common in licensed commercial cultivation: (1) facilities running reverse osmosis water, where the base water contributes essentially zero calcium or magnesium and the two-part base alone may not fully compensate at higher EC targets; (2) operations growing in inert media — coco coir, rockwool slabs, or loose rockwool — where the medium itself provides no mineral buffering; and (3) cultivars or phenotypes that express calcium or magnesium demand above what the standard Blended feed schedule provides, particularly during rapid vegetative stretch or peak flower development.
The 275-gallon tote format (SKU LQB-CM-275G) is sized for commercial operations with centralized fertigation — multiple rooms, automated dosing systems, or Dosatron injection setups — where buying by the gallon creates unnecessary handling overhead and per-unit cost pressure. If your facility is consuming multiple 5-gallon jugs per week, the tote format is the rational next step.
The Athena Blended CaMg formula is sediment-free and compatible with all dosing and irrigation systems, including fine dripper heads and Dosatron mechanical injectors. No mixing, no weighing, no dry salts — the liquid format integrates cleanly into any tank-mixing sequence. Shake well before use; use clean measuring instruments and do not introduce anything back into the container.
Dosing is flexible: the labeled range runs 2–10 mL per gallon depending on cultivar requirements, RO water conductivity, and growth stage. The Athena Blended Line feed schedule provides week-by-week reference targets across a 13-week program covering propagation, veg, flower, and finish. CaMg sits on that schedule as a conditional add-on — referenced where conditions warrant it — so you're not committing to a fixed dose regardless of plant signal. Monitor EC and pH after mixing all fertilizers and additives, and adjust pH to target after all inputs are combined.
Storage: keep sealed in original packaging between 45°F and 85°F. The 275-gallon IBC tote is standard pallet freight.
The Athena Blended Line runs as a two-part system: equal volumes of A and B per stage (Grow A+B in veg, Bloom A+B in flower), with supplemental products — CaMg, Balance, PK, Cleanse — added based on facility conditions and crop stage. CaMg is not a base nutrient; it is a precision tool. Operators running RO water and coco or rockwool typically run it throughout all stages at a dose calibrated to their source water and target EC. Operators on moderate municipal water in amended media may use it only during peak demand windows.
For facilities standardized on the Athena Blended program, consolidating CaMg purchasing through HSC at tote scale keeps your cost-per-mL down and eliminates the procurement friction of repeated small-volume orders. HSC maintains direct accounts with Athena, so you're accessing wholesale pricing without going through additional distribution layers.

Not always — the two-part base formulas provide calcium and magnesium as part of their mineral balance. CaMg is a supplemental product for situations where the base alone is insufficient: RO water with near-zero source Ca/Mg, inert media like coco or rockwool that provide no mineral buffering, or cultivars with elevated demand during heavy growth or development phases. Consult the Athena Blended Line feed schedule and monitor runoff EC and plant response to determine whether supplementation is warranted in your specific setup.
Yes. The formula is sediment-free and engineered to be compatible with all dosing and irrigation systems, including fine dripper heads and Dosatron mechanical injectors. It should not be used with electronic EC-based injection systems that require extremely low-viscosity, zero-particle solutions without first confirming compatibility with your equipment manufacturer.
The labeled application range is 2–10 mL per gallon of water, applied during all growth stages as needed. The precise dose depends on your source water's baseline Ca/Mg content, your growing medium, cultivar demands, and the EC target for that stage. Reference the Athena Blended Line feed schedule for stage-specific guidance, and calibrate from there based on plant response and runoff readings. The tote is typically plumbed into a Dosatron or bulk injection station for continuous high-volume use.
Yes. While it is particularly useful in inert media (coco, rockwool) and RO-water systems, CaMg is compatible with any growing method — recirculating hydroponics, DWC, soilless/peat-based media, or soil. In amended soils or media that already provide moderate calcium and magnesium, supplementation needs will typically be lower or absent; in those cases, plant tissue signals and runoff analysis should guide dosing decisions.
For commercial facilities consuming CaMg continuously across multiple rooms or irrigation zones, the 275-gallon tote reduces per-mL cost, eliminates repeated small-volume procurement cycles, and minimizes handling. HSC holds direct wholesale accounts with Athena, which means you access better-than-open-market pricing without layering additional distribution margin.
