Hey =D Great to hear! Thanks for the rep!
To answer your beginning question, as I failed to do just before (thinking you were the guy above my post) Yes, you can use the same amount for flowering. The "100w" guy who posted is correct, you want to make sure you have "enough" light to which anywhere producing nuggets is exposed to direct light, or at least not sitting in the shade. You dont technically have to have so many "watts per plant" but just max surface area of light exposure on the plant.
For instance, if you want to grow a plant with 1 little shitty 100 w cfl, you can, by all means, but you would have to do a complex combination of topping and or LST in order to spread the surface area of your plant so that every bit of the plant benefited from the light exposure. However, if you just left 1 plant under 1 bulb, untouched, all of the nugs between the nodes would stretch to the light, the plant would end up looking like a candelabra type thing and you probably would get such a tiny harvest it wouldnt have been worth the effort.
To clarify though, it is said and is proven, that the more lumens (light) that you give to your floweing plants, the bigger your yield will be. Once again I am not educated on this, its just information taken from diff articles I have read.
So ya its okay to use 4 100w soft whites in place of your 4 daylights when flowering, i dont think you will have an issue. If you do, simply purchase the tiniest soft white CFL you can find with a thin little cord and hang it in the "jungle" of the plant aka the middle without touching the foliage.
