LEVEL 07 · LESSON 01
What changed?
See it
Troubleshooting begins with observation and comparison. Instead of asking only ‘what is wrong?’, ask what changed in plant material, medium, vessel, environment, timing, handling, location, or source between the current culture and an acceptable reference.
Understand it
Record observable facts before causes.
Compare affected and unaffected cultures when possible.
Time and batch clustering can reveal patterns.
Important boundary
Avoid changing several variables at once before documenting the baseline.
Try it
Explain the concept in your own words, then identify what plant, explant, stage, units, source, or observation context would need to be preserved before applying it.
