Next year you should go full organic.. If you did not feed them during veg and they got like that and stayed green with no deficiencies then that's pretty good.. If you wanted to stay full organic into bloom then you could've thrown some bat guano on top of soil and water it in ( High Phosphorus for budding) and watered with molasses or brown sugar mixed in.. You probably new this though and maybe just chose chemical.
Either way nice job. Imagine if you fed them a few worm casting teas during veg! You would have the same size plant as my middle one lol.
