Adding more light for flowering?

Planning on my first grow of 1 plant and I was planning on buying 2 of these (4 bulbs total)

http://cgi.ebay.co.uk/2-x-45w-Blue-...edsBulbs_JN&hash=item2eae903026#ht_2732wt_951

using 2 45W 6400K to veg and then come flowering add the 2 45W 2700K to make 4 bulbs total

is adding this much light mid grow ok, or will it shock the plant or anything? Should I just remove the blues after veg and use red only?

Also how does the wattage look for 1 plant?

Thanks

I think you have the right idea, just add the two new bulbs and everything will be fine as long as the ventilation is good enough.

so doubling the ammount of light mid grow is OK for the plant?

The plants will love you for it.

you can quadrouple the amount of light and still could add more.
