Hey Omerta. It looks good for eighteen days bro. Let that baby veggie awhile longer like at least four weeks then slap her into 12/12. Hope you got a hid light to put on her during flower, will make a huge difference in the yeild of her. Keep up the good work and good luck with your first grow. It will be a learnig experence. It took me three grows to get my room lined out. Learned on my own how the plants act and what they need and when they needed it. Reading is very inportant but learning first hand about the situation is best.
