I don't think additional light on the rest of the plants in the room is ever a bad thing. The additional blue if anything will toughen up the stalks allowing more weight. No need to worry about separating them. The more the merrier when it comes to lighting. As long as you keep can the temp under control its all good. I've heard good things about 3000k MH bulbs when used in addition to HPS.

Stopped in my local horti- shop yesterday and asked. Interesting theorys. I was/am considering adding another light fixture to my flower room. Would using a MH in one end of the flower area and moving the plants that are closest to finishing under that light improve my yield and trichome content? Currently the flower area is a 1000 W HPS.
