Most likely diagnosis

Early root rot risk from low oxygen in a Kratky tomato

This tomato looks like it’s suffering from a hydroponic root problem rather than a leaf disease. In Kratky, whole-plant drooping usually means the roots are not getting enough oxygen, often from warm reservoir water, low air gap management, or roots starting to brown/slime. Your note about one bucket still declining after shading also fits a stressed root zone more than a simple sun issue. The slightly high pH can add extra stress, but it is probably not the main cause of the droop.

Expert move today ✅

Stabilize the root zone today

Act gently and focus on oxygen, temperature, and root inspection.

Check root color and smell in the worst bucket first

If roots are brown/slimy, remove bad roots only if they detach easily and do not tear healthy roots

Keep the reservoir shaded and as cool as possible without blocking all light to the plant tops

Differential diagnosis

Also possible, but less likely

Heat stress raising root-zone temperature

pH drift causing nutrient lockout and weakness

Severe water level imbalance between buckets or one container running dry

Targeted checks 🔎

What would prove it

Lift the lid and inspect roots: healthy roots should be white to cream and smell fresh

Brown, slimy, or foul-smelling roots confirm root rot risk

Check whether the problem bucket has a much warmer reservoir than the shaded ones','See if the droop improves overnight - heat stress usually rebounds, root problems often do not

Next expert check-in ⏰

Within 24 hours

Compare all buckets

Inspect every plant’s root zone and water level. The one that stays droopy is usually the one with the worst root oxygen problem or the warmest reservoir.
