First time grow from seed

Hey guys is it normal for my plant to be growing leaves I between leaves? I've only seen plants that grow 2 sets of leaves then two to the other side.. Well she has leaves growing diagonally betwee them and then leaves growing between those.. Lol just a question.. Also who does he leaves look like that? Someone mentioned it can be a PH problem.. Could that be it? I'll upload a few pics

Some pics of her today

Hey guys so I woke up this morning and saw this!! Just want to know is she showing her sex yet? I saw little hair looking things growing from her so I thought I'd ask.. She is 2 weeks and 2 days since I put her under light.. Also imo she is growing really bushy to be 2 weeks old is this good? Any help/advise will be appreciated..

Also when do you guys think I should transplant her into a bigger container? I'm planning on using a 3 gallon smart pot..
