pk 4/10 and big bud help??

hi just starting flowering and plan to use pk 4/10 along with bid bud bloomer and overdrive i have started using the pk 4/10 from the 1st day off bloom which i know know is a week too early, but what can i do?? just looking some help and advice on using the pk and bid bud together when to use each ot them thanks

off AN website.........Hammerhead should not be applied when growers utilize products such as Bloom Booster Pro, or Bud Blood to supplement the first two weeks of a blooming cycle; it is simply redundant. Hammerhead can be used in weeks 3 -5, following the use of such early-bloom enhancers as Bud Blood and Bloom Booster Pro, when their use is discontinued.

I don't see big bud mentioned in there but seems it would be redundant too. I run dyna gro mag-pro and base nutrients up to the second week when I add big bud, I then add nothing but the big bud and base bloom. after week 4 (last week of big bud) I'll go back to mag-pro and cha ching and base nutrient. you can certainly email AN and they are very helpful and know their product. Running two bloom boosters at once though seems a waste.
