Fox Farm Trio

So i just got my fox farm nutes, never tried em before- grow big, big bloom, and tiger bloom. Lookin at the back i see instructions for use every watering. So i'm wondering, how often do u f.f. users feed with these? Typically I feed once a week so should I just feed once a week with the reccommended 'heavy feeding' dose, or do it everytime with the 'every watering' dose?
