How big should the pot be?

Minimum 5 gallons for most; 10+ gallons for larger indeterminates. Drainage holes required.

No — it compacts. Use potting mix made for containers.

Often overwatering, underwatering, or need for feed. Check soil moisture first, then fertilize lightly.

Tomatoes want strong light. A sunny balcony or south window plus grow light works better than a dim room.
