If new growth looks iron-deficient but your EC and pH are dialed, stop adding Fe. The issue is usually over-saturation, not nutrition. Wet media starves roots of oxygen, shutting down micronutrient uptake even when iron is present. Chasing nutrients won’t fix it—restoring air to the root zone will. Dial in irrigation and Volumetric Water Content (VWC) to bring the plant back into balance. This isn’t a chemistry problem. It’s a physics problem.
