| Target EC, mS/cm | 1.87 |
| Element | ppm (mg/L) |
|---|---|
| Fe (железо) | 1.1 |
| Mn (марганец) | 0.1 |
| B (бор) | 0.3 |

| Cu (медь) | 0.0 |
| Mo (молибден) | 0.1 |
The values above are the target element concentrations in the final solution. To obtain them from your fertilizers, click "Open in calculator": it computes salt weights for the needed water volume and starting EC.
When raising EC, increase all elements proportionally except phosphorus. Keep pH within 5.5–6.5 for most hydroponic crops.
