Leaves often show root problems.
Yellowing, curl, necrosis, slow growth, wilt, and deficiency-like symptoms can all be caused by root-zone issues. Root checks must come before aggressive nutrient corrections.
Printable root-zone tools
The first root downloads focus on watering and dryback, pH/EC troubleshooting, root-zone problems, and deficiency versus lockout comparison.
Use this alongside the 3D Atlas to distinguish the root cap, meristematic region, elongation zone, and differentiation/absorption region.
Read roots with the environment
Pair anatomy with root-zone temperature, substrate moisture or mass trend, irrigation timing, oxygen/aeration context, pH, EC, and the plant response above ground.
