Using Big Bud for first time

Hey what's up everyone? Been checking the site now for a couple weeks and have really found awesome info on everytrhing to do with growing......Keep up the great work guys.... I have got one quick question i'm about a week before flowering(plant doing great for first grow) and was wondering when i switch to flowering nutes is it ok to just use Dr.Hornby's Big Bud on its own or should i use another form of nutes as well???? thanks guys

add big bud to your bloom nutes. big bud is not a base nute so no good on its own i normaly start with big bud at about week 3 of flower if that helps.

Thanks for the info Spike....what would be a good base nute to use ...i know u wanna keep the Nitrates close to zero...any recomendations????
