Is my Sequoia a goner?

Ok so I purchased a Sequoia germination kit from Johnsteen Seed Company and started it over winter break. I had to stratify it for 20 days. Soon after bringing it into a warm green house I noticed a small root on the side of the clear kit. A couple days later a few green needles (I know they aren't needles) poked throw. I then transplanted it into a larger pot. In doing this I think I broke part of the root. Now (the next day) The tips of the short needles are looking not too good... Is it too late or is there something I can do?
