A/B Stock Split ?
Why A/B?

Ca²⁺ + SO₄²⁻ → CaSO₄ precipitation. By separating Part A (Ca) from Part B (SO₄, PO₄), high concentrations stay stable.

Never mix dry A + B together.

Element Deviation from Target ?
Element Deviation %

Shows how close each element is to the target ppm:

• Green (±10%) = ideal
• Yellow (±20%) = acceptable
• Red (>±20%) = re-solve with different compounds

Nutrient Ratio Analysis ?
Nutrient Ratios

Compares your formula to scientific reference frames (Bugbee, Hoagland).

Ratios represent the relative balance of macro/micronutrients. Green = matches reference, red = deviates. Slight deviations are OK for crop-specific optimization.

Chemical Compound Library ?
Price & Cost Tracking

Prices are fetched from supplier APIs or manual entry. Update prices regularly for accurate cost estimates.

Cost tracking helps compare formulas by final production cost, not just nutrient accuracy.

MQTT Configuration ?
Dosing & MQTT

MQTT is a publish-subscribe messaging protocol. Connect to your broker to send dosing commands to remote pump controllers.

Configure the broker address, port, and topic prefix, then use "Publish" to send the current formula to all mapped pumps.

MIXING GUIDE ?
5-Step Process

Prepare containers → Part A (Ca) → Part B (SO₄, PO₄, etc.) → Store → Final reservoir dilution.

Follow each step carefully to avoid precipitation.

Solve a formula first to generate step-by-step mixing instructions.

⚠ CHEMICAL ALERTS ?
Compatibility Warnings

Alerts check for precipitation risk (Ca²⁺ + SO₄²⁻), solubility limits, pH issues, and nutrient toxicity.

A/B split automatically prevents precipitation.

Select compounds to check compatibility.

Stock Concentration

All volumes assume a 100× concentrate. The final mixing step dilutes 1 part concentrate with 99 parts water.

For 50× or 200× concentrates, multiply/divide all volumes proportionally. Higher concentration = smaller volumes but less precision. Lower concentration = larger volumes but easier to measure accurately.
