To be honest with you man you should just get some compact florescents. Alot more efficient and better for ur precious lil seedlings! they are very easy to fry and you shouldn't do any pruning or cutting until your plant is at least 8-10 inches tall or it will stress it or let in desease.
Order urself some new seeds fo show and just start from scratch! But you should definately educate yourself on light cycles and shiot because that is the most important thing for your plant. Also when your flowering under 12/12do not disturb their dark time at all it should be completely dark...
