Pre-flower has shown female should I put straight into flowering stage?

My 6 plants on my DWC system and under a 400w hps light. This morning they started to show pre flower and are female... Should I keep in veg for a bit longer or should I put them straight into flowering stage? Thanks for any answer, info, or tips....have a good one!

Pictures would be nice..info on how old they are and space working with would be nice too.
With no other info @ this time...I say GO For It !

They are 3 or 4 weeks old im working with a big closet but I am going to make a giant grow box for flowing for the smell and your a carbon filter. I'm using a 400w hps grow light as I said before....I'm using bc gro and bc boost as nutes....anything else you would need to know...here are pics of my whole lot. I couldn't take a pic of the pistils that are showing from pre-flower .... I have had 2 successful grows but never have I had preflower...tell me what you think thanks

ALL OF THE PLANTS IN THE PICS ARE ALL GREEN AND NO YELLOW!!!!!!! That is the camera and lights playing tricks

These pics are upside down I have no idea why because they were not taken upside down and I have no clue how to fix that so sorry

LBUMP!!! Here are some pics...and here is a pic of the preflower

Looks good...flower them.

Thanks fore the advice I plan on flipping to 12/12 sunday! So if anyone has any other advice for me it will be noted thank you in advance!
