Now that your tomato seeds have sprouted and you’ve thinned the extras, it’s time for a quick check-in. This isn’t just about admiring your baby plants — it’s about noticing the small signals that tell you how they’re really doing.
What Healthy Seedlings Look Like
- Bright green leaves with no yellowing or spots
- Short, thick stems — not tall and spindly
- Strong upright posture, not leaning toward light
- Consistent new growth, especially true leaves forming
If your seedlings check these boxes, you’re doing great!
What to Watch (and Fix)
- Leggy stems = not enough light. Lower your grow light or move them to a sunnier location.
- Yellowing leaves = overwatering or nutrient deficiency.
- Drooping = could be underwatering, overwatering, or sudden temperature swings.
- Mold or algae on soil = too much moisture, not enough airflow.
Fixing small issues early makes a big difference later — tomato seedlings bounce back quickly with a little care.
Keep the Growth Going
- Stick to a consistent light schedule (12–16 hours/day).
- Let the top of the soil dry slightly before watering again.
- If you haven’t already, consider a diluted liquid fertilizer after true leaves appear.
