Diagnosis
Likely calcium uptake stress
mediumRust spotting plus feed/runoff context suggests calcium uptake stress before a true shortage.
Recheck
Recheck new growth in 48 to 72 hours.
Other supported possibilities
Light stress amplifying damage · mediumUpper-canopy stress could be sharpening nutrient symptoms.
Next 24-72 hours
- 1.Measure pH/EC and hold feed steady for next irrigation.
Check now
- 1.Measure input and runoff pH before adding supplements.
- 2.Compare new growth against already damaged leaves.
- 3.Check whether spots spread after next irrigation.
Nutrient / root zone
- 1.Keep feed strength steady until pH is confirmed.
- 2.Make one small correction at a time.
Environment
- 1.Keep light distance and watering cadence stable during recheck.
- 2.Avoid large humidity swings while leaves are stressed.
Prevention
- 1.Log input and runoff pH/EC weekly.
- 2.Keep feed changes small enough to isolate cause and effect.
Target ranges
Coco pH5.8-6.2Use current medium when checking feed/runoff.
