Indoor Tomato Vines: Leaf Curl Causes and Fixes

Leaf curl = poor drainage/overwatering (roots can't absorb O₂/nutrients), excess nitrogen, or aphids. Fixes: reduce watering, use low-N high-P fertilizer, check for aphids (insecticidal soap). Pinch tops to control height; let suckers fill in.

Indoor Tips

Pots need excellent drainage.
Grow light 2 ft above, adjust as plants grow.
Watch for pests brought in from outside.

Consistent moisture and balanced feeding prevent curl.
