Calcium and Magnesium Supplementation in Hydroponics
Cal-Mag fixes calcium and magnesium deficiencies caused by RO water, high-K formulas, and LED lighting. Standard dose 1–2 ml/L from week 3 onward.

EC Management in Hydroponics
EC (electrical conductivity) measures dissolved salts in nutrient solution. Targets range from 0.8 (lettuce) to 3.5 (fruiting tomato). Drift accumulates daily.

Hydroponic Macronutrients — N, P, K, Ca, Mg, S
The six macronutrients in hydroponics and what each one does. Nitrogen drives leaf growth; potassium drives fruiting; calcium and magnesium fail first.

Hydroponic Micronutrients Reference — Fe, Mn, Zn, B, Cu, Mo, Cl
The seven hydroponic micronutrients — iron, manganese, zinc, boron, copper, molybdenum, chlorine. Iron deficiency is the most common; boron the most toxic at excess.

Mixing Your Own Hydroponic Nutrients
DIY Hoagland-style nutrients use stock solutions A (Ca), B (P, S, micros), and CaNO3. Cost runs 70–90% less than commercial; precision is comparable.

pH Management in Hydroponics — The Complete Guide
pH controls every nutrient uptake. Complete guide to the 5.5–6.5 sweet spot, testing, adjustment, drift prevention, and per-crop targets.
Frequently asked
- What EC should my hydroponic nutrient solution be?
- Most crops sit at 1.2–2.4 mS/cm; leafy greens such as lettuce run lower, at 0.8–1.2 mS/cm. Each plant profile lists its own range.
- What pH should hydroponic nutrients be?
- 5.5–6.5 for most crops. Measure pH after the nutrients are mixed, because dissolving them shifts the pH.
- How do I mix hydroponic nutrients?
- Fill the reservoir, add each nutrient part separately and stir between them, then measure EC and adjust pH last. The nutrient calculator gives the dose for your volume.
