Lighting/flowering question, need your opinion

Ok so I have my closet split in half with the top being my flowering using a 400w hps, and the bottom my vegging using a 400w mh.

My plants up top are about 6 weeks into flowering.




And my plants below have been vegging for however long. This pic is about a week old before I have my mh light.




Now I figure my plants up top only have about til the end of the month before they are finished so I wanted to start flowering my plants that are vegging to get a jump on it.


Would I be better off just turning my vegging half onto 12/12 and begin to flower them with the MH, or would it be better to switch the plants and finish my now flowering plants off the last few weeks with the MH so the vegging plants can begin flowering under an HPS?


But I'm not sure if it makes a difference either way.
What do you guys think?

Those are looking good! The stems are fat on some of those and the flowering looks beautiful! Sorry I can't offer more help, just wanted to compliment your green thumb!

Thanks for the compliment.
Anybody have an opinion on this?

It dont matter on the light time is the key a plant has built in timer so when you move to 12/12 itll start flowering then later move them to hps, i'tll be ok. Nice plants keep it up.
