Most likely cause
A best guess from your answers, not a definitive diagnosis. If it doesn't match what you're seeing, compare all causes.
Root-bound plant
How to tell
Growth was fine, then plateaued; roots visible circling at the bottom of the pot
Fix
Transplant into a larger container
Temperature too low
How to tell
Growth slows dramatically below roughly 60°F, especially at night
Fix
Bring ambient temperature up, particularly if growing outdoors in a cooler season
Normal transition period
Normal — not a problem
How to tell
A brief pause right after transplanting or right after switching light schedules is normal, not a problem
Fix
Give it a few days before assuming something's actually wrong
