NutriCalc Visual Diagrams

1️⃣ Mixing Equipment Setup

Shows the recommended equipment and container setup for hydroponic nutrient mixing.

5-Step Mixing Equipment Setup DI/RO Water ① Start Ca Part A (Calcium) ② Mix Part A SO₄ PO₄ Part B ③ Mix Part B Part A Store Part B Store ④ Store Final Reservoir ⑤ Dilute 1:100 ⚠️ Critical Rule: Never mix Part A + Part B as dry chemicals. They precipitate together. Keep separate until final dilution.

2️⃣ Precipitation Chemistry

Why A/B split prevents calcium sulfate crystals from forming.

Why We Split A/B Solutions ❌ If You Mix Dry A + B Ca²⁺ SO₄²⁻ CaSO₄ (Precipitate) ⚠️ Cloudy, unusable Nutrients lost, solution concentration incorrect ✓ With A/B Split Ca²⁺ Part A SO₄²⁻ Part B ✓ Clear, stable solution Ca²⁺ and SO₄²⁻ separated Only mix at final dilution

3️⃣ EC Meter Scale & Crop Ranges

Quick reference for electrical conductivity targets by crop type.

EC Target Guide by Crop 0.8 1.2 1.8 2.2 2.8+ Seedlings Leafy Greens Most Crops High Demand Extreme Lettuce (Seedling) EC 1.2–1.8 Lettuce (Grow) EC 1.6–1.8 Tomato (Veg) EC 1.8–2.0 Tomato (Bloom) EC 2.0–2.4 Strawberry (Bloom) EC 2.2–2.8 💡 Tip: Start low (1.2), increase gradually as plant grows Too high EC causes burn; too low causes deficiency

4️⃣ Part A vs Part B — What Goes Where?

Visual breakdown of which chemicals belong in each container.

A/B Split Chemistry PART A (Calcium Container) Calcium Nitrate (CaNO₃) Potassium Nitrate (KNO₃) Magnesium Sulfate (MgSO₄) Micronutrient Mix Iron (Chelated) Mix FIRST in water PART B (Sulfate/Phosphate) Potassium Sulfate (K₂SO₄) Monopotassium Phosphate (MKP) Magnesium Sulfate (MgSO₄) Boron (Boric Acid) Zinc, Copper, Manganese Mix SECOND in water ⚠️ NEVER: Mix Part A dry + Part B dry = Precipitation

5️⃣ Stock Concentration & Dilution

How concentrates work and how to scale for different strength levels.

Concentrate Scaling Guide Example: 100× Concentrate (Default) Concentrated Part A & B 1 Part Final Solution (1:100 dilution) + 99 Parts Water Scaling for Different Concentrate Strengths 50× Concentrate 50 mL → 2.5 L (Larger volumes, easier to measure) 100× Concentrate 30 mL → 3 L (Default, balanced) 200× Concentrate 15 mL → 3 L (Precise scales required)
