should I use 2xhps for flower or 1mh and 1 hps?

I'm about 6 weeks in 12/12 running 10-11 week strains and have run out of space under my 1000w hid so i got another 1000w and the way they are positioned there is a large amout of the canopy that gets light from both bulbs and was wondering if the dual spectrum would be more beneficial or if i should just run both hps?

The MH won't produce the weight but it will bump the frost compared to HPS.

I'm tempted to try combining 315W LEC with HPS on the same theory...

Thanks that is about what i expected to hear. but if i were to mention the mh bulb is a Hortilux Blue would that sway your opinion at all regarding yield? The way things are frosting up I'm not worried about potency to the point I'm willing to run another 1000w just to frost them up a little more and hardly make any more yield
