Plant preflowerd ahead of schedule

RIU what do I do when my plant has preflowerd way ahead of schedule. I've been running her under 18/6 since 6-9-13 and I wanted to keep her that way till 8-15-13 but she's already shooting pistils her first ones showed 7-17-13 so should I induce her into 12/12 or can I keep her under 18/6 I'm trying to get a bigger yield than my previous grows.

You can most definitely keep her under 18/6 on my latest grow I kept one over a month with the preflowers showing and from what I understand you could keep her vegging for years

Oh wow yea I don't need to veg her quite that long lol but yea I'm thinking of pushing it till the end of August I have 10ft ceilings so hopefully ill be ok with a lil lst

Mine have doubled and I'm just starting second week of flower
