Hello,
I have included pictures of the leaf disease on my tomato seedlings. This kind of damage has usually showed up later in the season, but here it is on these seedlings.I am hoping you can help me identify what it is so I could try growing varieties that are resistant.
Thank you,

Hi Beyla, thanks for the question.
This looks like it could be sun burn or burn from hot lights. Have you had these outside? How are you watering, feeding? What type of medium (soil) are you using? Where your pots and tools disinfected? Did this happen suddenly? Is it spreading? Sorry for all the questions. Hopefully we can figure it out quickly.
Hello, thank you so much for your reply, and I'm sorry it took me such a long time to get back to you. My child was having a medical emergency, and ended up in the hospital for a month and a half. I am just now beginning to catch up again!
I think you are right about it being light burn. I did have them under lights and wasn't paying much attention to them because of the unfolding crisis with my child. The reason I thought it was a disease is because for the last few years all my tomatoes have, later in the summer, had their leaves discolor and die. It usually starts from the bottom up, and I thought at first glance that it looked like what I was seeing on these seedlings. Now, however, I got them into the ground and they are all looking healthy and green. I guess if the discoloring thing happens again later this summer I will send you more pictures then!
Keep a close eye on these plants. If you see problems on your lower leaves, it would be a good idea to remove them and spray the plant with a copper fungicide to prevent further infection. Most likely you are seeing a soil borne disease that transfers to the plant via rain splash. Take a look at the following link:
