Skinny plant

I have a plant that was planted from a badseed and sprouted in mid september. I kept it in the windowsill for about 3 weeks or so then put it in a little closet with some CFL's. I put it on 12/12 about 6 weeks ago and it showed sex about 4 weeks ago. Since showing sex it's doubled in size; it's about 32" tall now, but it has minimal side branching and started growing a cola between 2-3 weeks ago. It has bud sites at every node with tons of long white hairs and about a 3" cola on top but all the sites are mostly white hairs and the cola is skinny. I was wondering when it acutally started flowering? When it showed sex or when it started a cola? Also what kind of yield might be expected from a plant of this size with tons of bud sites? I was planning on harvesting for xmas but have abandoned that idea.

Do u Have any pics?

if is has white hairs and a cola - it is a female and has been showing sex ever since you first saw the white hairs. It has been flowering since the switch to 12/12.

flowering usually takes at least two months (8-10 weeks) from the time you switch to 12/12.
