Beginner Gardening: Tomatoes leaves drying up, 2 by TontoRodriguez

I apologize in advance for the length of this question. I am a new urban vegetable gardener. First timer! I have spinach, lettuce, kale, and peas; all doing fine. I transplanted my tomato seedlings 2 weeks ago (after 7 weeks) and it seems that they, for the most part, aren't doing too well.
I only "hardened them off" for three days. Raised beds, good pH. I transplanted 2 each of 6 different varieties of heirloom tomatoes. I'm pretty sure that some of them have suffered from sun-scald. There is white on some of the leaves, so my best guess is sun-scald. I will try to add a couple of pictures if I'm allowed.
I am in zone 6 (eastern KY) and yes, I transplanted them before the "last frost date," but I am in tune with the daily weather and we are experiencing an early spring, of sorts. No frost (not even close) since I transplanted them. I have pinched off some of the "sun-scalded" leaves, thinking it was the right thing to do.
So, my two-part question is - Am I right in thinking it is sun-scald. and pinching off the damaged leaves? And, can the tomato plants still survive and produce a nice harvest?
Thank you very much!
