What EC and PPM levels should I target with Cronk Nutrients?Updated 4 days ago
Target EC and PPM levels vary by growth stage:
Seedlings: 0.4–0.8 EC (200–400 PPM)
Vegetative Stage: 1.0–1.6 EC (500–800 PPM)
Flowering Stage: 1.6–2.2 EC (800–1100 PPM)
Late Flower / Ripening: 1.0–1.4 EC (500–700 PPM)
Always monitor runoff EC to prevent salt buildup and adjust feeding strength gradually.
