Long term effect of cold on tomato seedlings

We have had a very cold spring and my tomato seedlings have spent most of their time in 45 to 55 degree temps. Except for germination @ 80 degrees. The plants look very good except for a lot of purple under the leaves. The stems are stocky and the leaves are very full, but are dark green on top. When I transplanted them into 4" pots, they had great root systems as well. They have been kept within 2" of the florescent lights.

I have been giving them a weak solution of 4-12-4 so I don't think the purple is from a shortage of "K". Probably just cold and being young.

My question is: With being held at cold temps for so long, is there any long term negative effects on the plants future performance?
