Fox Farm GB and BB--used together?

OK, I just got my Fox Farm Grow Big and Bud blaster. I'm a little confused by the charts, but I'm newbie, so everything confuses me.
I've got two sativa in 12/12 now for a week.
When it's time to feed, am I supposed to use both products, or just one at a time? When I'm in flowering, just Bud food, or mix them into one container and use that to feed every other watering?

Thanks to all you guys, I've gotten this far just on what you've told me. 2nd grow, and it's looking very good. Take a bow, Mogie, Sgt. Stoner, Widow Maker, viredd.

Grow big is for vegging

Bud Blaster is for flowering

And I am 97 percent sure LOL

Yeah - don't feed them grow big while they are flowering. they don't like this, and i know from personal expierence.

Thanks, guys. How do you wait for 2 months without going nuts? It's like having kids.

No shit. Esp when you cant get smoke. I've got about a month left, from oct 20th, it's no walk in the park - but impatience will kill your ladies.

p.s. don't use those ferts all full strength off the bat, start with 1/4 and work up.

Yo, russor, I feel your pain.
I've got two in 12/12 for a week, I think one is a male, but not sure yet. I sure don't want to murder the wrong one. I've got two clones of each, so I should be set up for the next round, unless I kill them.

dont rule ut a male yet. wait for hairs to pop out, cut it when you see the first cluster forming so you dont get pollenated.. and be careful moving it out of your grow room as to not pop any sacks or spread pollen

Yah. My first grow I thought I had a female with flowers, and when I shook it I got a nice cloud of pollen.

Hello Bye

Pollen is from a male.......not from a female..check the illustration below
It's not a human child...it's a plant.......I swear to god it is....
do you think you could grow a tomato...GOOD...then you can grow anything..
Theres a wealth of information out there....explore, young ones, and become beholders of the fine green....AMEN
