I transplanted these tomatoes grown from seed on my own about 1.5 weeks ago. Today I noticed that the leaves on all four of them have the same symptoms. I am not sure of the variety because I planted a different types,. Only 2 of the 4 are the same type. Pictures are in the links below:

The tomatoes are three feet from one another, not touching, and about a foot tall. Up until this point they have looked healthy. I hardened them off for a couple days before transplanting the tomatoes. They were outside 2 to 3 hours the first day and then 5+ hours for the next two days. . After three days of hardening and not noticing any wilting/issues I transplanted them. I have not overwatered, and it has not rained in the past week. When I have watered I always made sure to not get the leaves wet. The discoloration is only noticeable on the lower branches/leaves and new leaves are growing at the top of the plant. I use fertilizer, plenty of compost, top soil, garden soil, etc. and have experience with growing tomatoes, but this was the first year I tried growing them from seed inside.
