Cutting Seedling Leaves???

It is currently day 18 of vegging and my seedling originally looked fine to begin with but it is now showing signs of heat stress. I lowered the seedling from the lights but the damage was done. If you ever had heat stress you would know that the leaves would become curling upward and become stale and crunchy. The seedlings two main leaves were crunchy and were curling upward but the second set of leaves that come out of the top are fine. Since the second nodes came out I decided to cut the part of the leaves that were crunchy on the original two set of leaves. I was wondering is this okay and will my plant survive or should I just kill it?????
