2 Autos & 2 Regular - What's best to go from here. Please help!

I'm on 30+ day since seed with two strains : Short Rider and Aurora indica. You can see some pics here checking my link on signature.
Right now I have a big dilemma :

1. Swich to HPS 600w dualspectrul since Autos have some buds and put the Indicas in other room ( it will use sunlight ).
2. Keep the 4 plants in the same old MH 400w which is mostly used for vegetative state and swich to 600w when flowering with the Indicas.

Please give me an advice. Thanks!

I'm back to 400w MH lamp and all the plants are in the same place. It was stupid to separate them, stupid move.
The Short Riders will get the same treatment like the Indicas and that's it
All the plants are great till now.

U cant go wrong with giving flowering or vegging plants MH and HPS... Thats the only way I roll, in varying ratios... More MH during veg, and more HPS during flower, but both during the entire grow... Better overall yields and results... U answered yer own question... Now, yer cookin' with Crisco!

I see. Now I have some heat issues from the 600w dualspectrum lamp so I need to bring back the cooltube. I have the cooltube becuase of the noise increase
