Is this a good nute combo?

I was wondering if this would be a good nute combo or not without having nute burn etc.
Last few grows i used the 6 fox farm nute line and loved it but was wondering if i could add humbolt's gravity for more density and humbolt's purple max for more crystials on top of it.
What do you guys think would go well with the fox farm line?
Was wondering about the "big bud" liquid nutes from AN.

are you growing hydro or soil? i do both, soil for the taste, hydro for the race, but with soil i use fox farm. 12 years of growing taught my fox farm works best with natural stress practices (you can find plenty in this site) also, liquid kelp concentrate and a product called super thrive. as far as hydro goes, i use nothing organic in my resivor, only the genhydro line. here, click the link for my latest creation, its a photobucket slideshow. enjoy, stay green!
