They look fine man...don't fret. Don't prune though, either.i vegged for 3 weeks because i don't have a high celing and they were a foot tall at 3 weeks, when i started 12/12, they quadroopled in hieght and are now 4 foot plus tall. they were vegged with 5500k lights so i'n not sure why they got so tall, i probably should have LST'd them.
