few questions from a newb

Hello guys. I'm a yung grower that has grown two plants previouslym the plant I have now is purple haze. Its 2-3 weeks old nd bout 7 inches tall. The leaves are decent. They're like 2-3 inches long and an inch wide. It has 3 sets of leaves but the third one is still opening up. It has three blades. And I think it has 5 blades. The stem is thick and the smell is already strong. Its under a 60watt incandescent cool white bulb that's bout 2 inches above the plant. Only one node is starting to grow side branches and that's the node with three blades. I was under the impression that there are 2 sets of three bladed leaves before the 5bladed appears but this one only had one. Is that normal? Its in mg so I don't give it nutes. Also will it grow side branches more often now that its possibly vegging? Sorry for the inability to post pics but please bare with me. On that note does this plant seem health or in need of something?

You don't grow with incandescant bulbs. The number of blades on the leaves means absolutely nothing.
