best light spectrum for autoflowering genetics?! (kelvins)

I know vegging you want cool blue, flowering you want warm white.

blue 6500k warm white 2500k

but what spectrum is best when autoflowering under 24/7 or 20/4 light cycles?
blue? whit? both?

never grown auto's but i can give you an educated guess
i would use a mix of both spectrums but mainly blue until you start seeing pistils
then i would switch over to mostly 2700k to finish her up

im thinking 24/7 on blue

then 20/4 or 18/6 on white!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ANY AUTO GROWERS HERE USING CFL'S!!???????
