Most likely diagnosis

Early root oxygen stress in outdoor Kratky, likely progressing toward root rot risk

This tomato looks stressed and declining, and in outdoor Kratky the most likely cause of sudden wilting after a period of good growth is low root oxygen leading into early root rot risk. The timing fits especially well when plants are outside, totes warm up during the day, and the reservoir has been kept on the lower side or fluctuates. EC can look fine while the roots are still failing, so a normal 2.0–2.2 does not rule this out. The photo shows a leggy, yellowing, droopy plant rather than a simple feed issue, which points more toward root function than nutrient strength alone.

Expert move today ✅

Stabilize the root zone today

Protect the roots first. In Kratky tomatoes, once wilting starts, the fastest win is usually cooler, better-oxygenated solution and removing any rotten roots.

Inspect roots now and trim only clearly mushy, brown, smelly sections

Top up with fresh balanced solution if the level is low

Shade or insulate the tote from direct afternoon heat if possible without changing the plant position too much

Differential diagnosis

Also possible, but less likely

Heat stress from warm reservoir and hot patio conditions

Water level management issue in Kratky causing roots to dry or cycle poorly

Nutrient imbalance or lockout, especially if pH has drifted outside range even with normal EC

Targeted checks 🔎

What would prove it

Lift the lid and inspect the roots: healthy roots should be mostly white to cream and fresh-smelling, not brown, slimy, or sour

Check whether the reservoir water feels warm in the afternoon; warm solution strongly supports oxygen stress/root rot risk

Look for a rapid wilt pattern where the plant perks up at night or early morning but collapses in midday heat

Next expert check-in ⏰

Within 24 hours

Verify whether this is root failure or heat stress

Check root color, smell, and water temperature at the hottest part of the day. If the roots are brown/slimy or the reservoir is warm, treat this as root oxygen stress/root rot risk. If roots are clean but the plant still collapses only in peak sun, heat stress is a bigger factor.
