I would say some of it is from the cold but I'm not sure all of it is. If it is very warm during the day then freezing at night could do some damage, that looks to be the case in the second picture in the leaf on the right. The sun shining on the plants makes it a bit more difficult to see what's going on, I think there may be some interveinal chlorosis which suggests a nutritional problem (which you've had before, Sabrina). That can happen just because of cold soil but also high soil pH. There are a couple of things that are somewhat reminiscent of spring sickness but I'm not seeing it as totally characteristic.
Can you take any pictures without sun shining on the leaves, Sabrina?
