Help!i burnt a seedling

one of my small seedlings (week and a half) grew really quickly when i was away and it touched the light ,now its burnt a little on the tips of the first two jagged leaves. Is it game over or what?

Cut the burnt parts off and continue to care for it like normal. If it wasn't badly damaged it should recover, but as the saying goes... don't put all your eggs in one basket.

You should try to germinate as many seeds as you can, and kill off the weak as needed.
