Act on the strongest signal
Reduce salt stacking: increase irrigation frequency or runoff gradually, then verify the next two readings.Change one variable at a time. Confirm with plant response and the next readings.
1
Root-zone EC is substantially above input EC.Treat this as a trend signal, not a one-reading command.
2
Day VPD is outside the 1.05–1.3 kPa stage target.Keep the rest of the recipe stable while you verify it.
