It’s growing a lot and I see it’s putting new roots too. A while ago I saw the branches were curling inward but didn’t think much of it but now the bottom leaves are yellowing with brown splotches. Could it be blight?
for context, I bought the plants, transferred them into a raised bed three weeks ago. Only watered them whenever I saw the soil was dry but lately it has been raining pretty moderately. No fertilizer yet. I live in 9a Texas but the weather has been really mild (70-80 highs)

I’m guessing nitrogen deficiency.
Looks just like blight. Did you reuse the soil from last year?
Could be a few things. If you haven’t fertilized yet, you’re behind and need to do that. Also overwatering can do that….now one thing I’m not sure about is this setup, looks like a cardboard box inside of a tub? Is there drainage? I’d be concerned the box is acting like a basin and trapping the rainwater.
Avoid using cardboard for tomato plants. Cardboard is really good environment for Early Blight Fungus.
What brand of soil did you use?
This is 1000% a nitrogen and maybe magnesium deficiency. Nitrogen deficiency always starts from the older leaves going up. But other notable possibilities would be not enough sun or over watering but I don’t think it could be over watering because that normally leads to yellow leaves all over
Trim off the bottom 3 sets of leaves
Since you haven’t fertilized yet, it’s definitely a nutrient deficiency. You would be fine with just using the water soluble “Miracle Grow Tomato Plant Food.” Since you haven’t fed it yet, you will probably want to use half of the recommended amount, and with half the recommended amount you can feed twice as often (half the recommended amount once a week as opposed to the recommended amount once every two weeks). The reason I recommended to use half the amount once a week is to not shock the plant with a large dose of nutrients. It should be completely fine though as long as you just give it some type of food and trim the most affected foliage. Good luck!
Yeah, blight! Spray w anti fungal. Pull off those bottom yellow branches and burn them. There is early blight n late blight n comes in when weather changes.
It’s early blight. Remove the lower branches and pinch off the flowers.
If it’s been wet I would lightly loosen up that mulch layer. I wouldn’t add fertilizer until weather is good and you’re getting good green growth out of the top.
You’re over thinking it like everyone else here. Prune those yellow bottom limbs, I’d bet it’s just from where soil splashed on the leaves.
Blight
That soil looks woody as hell. Throw some compost down or fertilize accordingly I’ll bet they bounce back
i’m really glad there are so many comments about too much water bc that was my immediate thought. that’s how my tomatoes looked when i overwatered. beautiful green leaves up top but yellow bottom. i’ve learned that it’s not just the amount of water but weather/evapotranspiration.
the rain did that. check weather, water (or don’t) appropriately. mild weather, mild watering. when it gets hot, they’ll be super thirsty. they’ll be fine and look great.
