Hey man I have been there, set up your new lite and let this plant get use to it for a few days. Then I would transplant it and bury it down a little bit so you dont have that much stem blowing in the wind. If it doesnt start turning around you can always try again. The picture of your plant does only look like its 1 week old with alot of stretch due to poor lighting but ya gotta start somewhere. Good luck and try not to get frustrated. Peace
