If you had dosed ferts the difference in growth would have been even more dramatic since carbon would have remained the limiting factor in the one tank while nutrients would not have been a limiting factor holding the Co2 tank from utilizing even more carbon.
The fact that there were no ferts used and yet the differences between the two were still so dramatic says a lot for what a fertilized, well lit, carbon enriched tank can do that a tank with a limiting factor just can't compete with.
