If they have long roots, you are already late transplanting. Be VERY VERY careful not to damage the roots! What kind of system are they going into? I'd transplant right away, but don't put them under the HPS until they stop curling. You can mist them lightly with SMC leaf wash or even MORE lightly with DILUTED neem oil or wilt-pruf to help them retain water better while they are adjusting.
