A community-garden soil model is weak on the training beds and still weak on the held-out beds. The held-out rows were sealed before fitting, so they did not leak into training. What is the team seeing?

Short Explanation
Think of a student who never learned the material, so homework and the quiz both look bad. Weak on training beds and weak on held-out beds is underfitting. Leakage usually makes lab scores look too good, and two weak scores do not cancel into a win.
Full Explanation
Underfitting is a model that never captured the pattern, so it is poor on training data and poor on held-out data. Leakage typically inflates lab scores, not a pair of weak scores, and this held-out slice was sealed. Overfitting looks strong on train and weak on held-out data. Two weak scores do not cancel into a successful fit.
