Default Blue leds for vegetative growth?

I read on some places that strong blue light is beneficial to vegetative, leaf producing growth in plants. I know having a reef blue tank probably look horrible but whats wrong with using an actinic or 20 k t5 for awhile the. Switching it out for a 6500 k bulb when the tank is grown out? Why dont we do it for dsm's which dont have the problem of co2 limitation? Needless to say ive already started a dsm using blue leds ao lets see where it goes.
