My last grow consisted of 2x 4000K Vero 18s and a BlackStar Flower(Check my Crowns thread for more details), so I have a little advice to provide you and others but I'm not sure it will serve you all any good, as every plant and light is different.
I wasn't satisfied with just the 4000K - not because the light wasn't red enough but because I hadn't tried out the 3500K and 3000K versions. From the charts given by Bridelux, the latters supposedly bear more reds, where the former carries with it more blue.
I plan to try them all together in a combinational array during the upcoming Cup Competition.
In short, you should try something similar as you can't go wrong with the Vero line.
O and something about the 4000K I used: I veggged my last lady for around 30 days, with my 2x Vero COBs up and running the last week of if. She stood no taller than 13 inches just before flower. After the first week of flower, I introduced some IR. She grew about to 30 inches tall after the second week. After budding, she stood around 40 inches and had to have her main head tied down.
I believe this crazy ass growth to be in part due to the available blue provided by the 4000K, with the rest being that IR fastens growth during budding.
