CFL to 150W HPS transplant troubles

I just transplanted my plants from small pots under CFLs to a 150w HPS in larger pots and Fox Farm soil.
After 3 days in the new setup, the plants look weak and a bit wilted. I have kept one of the plants under the CFLs, and it appears healthy and vigorous.

Is the 150w HPS not enough light for my plants? should I return the 150w and get a 250w?

The first picture is how the plants looked immediately after transplant. The second photo is current.

i had a plant growing under a few cfls and i switched to a 150w HPS sun system a few weeks ago and its just fine.. make sure its atleast a half ft away from the tops of the plants maybe more

Six plants under 150 watts will keep them alive, but pretty soon you won't see any changes in the plants at all. So yes, definately trade up for the larger light source. 50 watts per plant is a decent rule of thumb. Much less than that and your plants fight for light and end up wimpy and super low yielding.But don't get me wrong, 250 will be plenty for your op if everything else is in order. However, when dealing with much more watts, this rule changes. Light put off by say, a 1000 watt lamp is much more intense,per watt, than say a 150.
