I have 3 girls going two plants in one pot that seem to be vegging great and the third seems to be flowering in 16/8 sunlight would it be damaging to leave this plant in those hours on sun or should I be pulling it in after 12 hours and force the flowers

sorry not sure how to post my pics

One way to post pics is to go "advanced" (under post box) and then "manage attachments" . . . another way, click the 2nd from the left icon (top of post box)
You'll get it.

i have tried everything to post pics it keeps telling me that i am missing a security token or something but noone to explain this to me i'll keep trying though

Never heard of a security token. Good luck.
If that flowering plant is doing so without 12/12, I'd leave it as it is.

I finally fluked out and got a couple of my pics to upload ...have a boo and offer suggestions please
