First pre-flowers showing! When to switch to 2700k CFL's??

So this is my first attempt at growing and these forums have been very helpful!! Thanks guys!! Anyways...my first preflowers are poppin up in various locations on the plant and I was just curious to when I should switch my lights over to 2700k from 5000k?? And I haven't done any LST or topping/FIM techniques for this grow this far...would it be advised or recommended to do one to control height or is it top late? Thanks for your input! Here's a pic of her lady parts : )

You got a better pic mate? Any info on age/height?

congrats its a girl, it depends on what you want to do man, your still vegging it all depends on your height spacing and pot spacing you could start flower now or wait a month if you want its your plant, and as long as your vegging you can lst fim, top whatever you want. Just give it time to bounce back before flippin to 12/12

Thanks! And I should have said this in the original post but I've been doing 12/12 from seed. Basically I've read up on it and it can make your grow faster, yes less yield, but its my first grow so I wanted to kinda get a feel for it all without too much time : ) so I guess you could say its already in its flower photoperiod lol. Would it still be ok to LST? Height isn't a problem. What would be the least stressful? I've learned a lot just from this one plant though. Basically this one is sitting in my living room comet lol. It's super healthy considering the conditions : )

LST if you want to. It can't hurt. Do you have pics of your light setup? For me that would determine whether to Lst or not imo. She looks healthy

I would want too but I just don't wanna stress out the plant. I know it's called low stress lol, but I'll link a pic of the setup. It's from a couple weeks back but still the same lights setup. Basically have one shinning on top and the other 4 all around the sides.
