High all.. do I have to change the rez every week?!

My first 2-3 grows were with AN nutes.. what a PITA!
I changed to basically the Lucas formula with HW micro and things are much calmer. But I will say that those 2-3 grows, the stalks and branches were much thicker.. yield? don't know, I was happy enough not to let it all go to mold at that point.

Lucas says no rez changes; I change only at the beginning of each new run.

But now I have all these AN nutes (that cost ALOT of money) and was thinking about incorporating some of them, just to see.

When one reads the AN nute calculator, are they assuming a rez change each week? In the case of lets say BIGBLOOD.. only to be used in the first week.... is it BAD for it to be there the 2nd week?
Nute lockout, something or another?
