Field checklist
- Lift or compare container weight before watering.
- Check whether the top, middle, and lower root zone are behaving differently.
- Record last irrigation time, volume, runoff, and current plant posture.
- Separate wilt from heat/VPD stress and root-zone saturation.
- Watch whether symptoms improve, worsen, or repeat after watering.
Rule: watering is a root-zone decision, not a fixed calendar habit.
