I have yellowing leaves on my tomato seedlings. The ventilation in my growing area is not great, so I’m concerned that it is disease vs just over/under watering. I’m guessing it might be tomato leaf mold, but I’m not certain. Should I attempt to treat these seedlings or throw them all out and start from scratch? I also have leaf curling happening on a couple of my soybean seedlings grown in the same indoor area. Is it possible that these are the same disease, or just a second problem?
