I started two tomato plants around the same time and they seem to get similar light, water, and fertilizer. One is growing well, while the other is smaller and yellowing. What would you check first?
Why is one of my tomato plants thriving while the other lags?

Similar care doesn’t always mean identical conditions. A small difference in sun, warmth, drainage, or soil can add up, and a cold snap may have set one plant back more than the other. Check whether the slower plant’s soil is staying wetter or drying faster, and compare the light it gets through the day.

Take a close look at the roots and the growing medium before adding more fertilizer. A plant that’s yellow and stalled can be struggling with root damage or too much moisture, but the symptoms alone don’t prove that’s the cause. Let the surface dry a little between waterings and make sure excess water can drain freely.

Sometimes plants just don’t develop at the same pace, even when they’re the same variety and started together. If the smaller one is still putting out healthy new growth, I’d give it time and avoid trying several fixes at once. If it keeps declining, then check for persistent soggy soil, damaged stems, or pests.

I’ll compare the soil moisture and light over a few days instead of assuming the watering schedule is the same as the actual conditions.
