Couple questions about nutes

So I have started my first grow. It is in a stealth cab, three small 6qrt bubbleponic setups. Any way my question is concerning nutes. I went to the hydroponic store and got a bottle of FF grow big. It was in the hydroponic section, after getting home I noticed that on the feeding schedule there is two different formulas for the grow big, one being for soil, and the other for hydroponic setups. Well of course I picked up the one for soil. It is 6-4-4, while the other(hydro) is 3-2-6. I have not opened, or used any yet. Do I need to take it back and get the other kind(hydro)? The plants were germinated on the fourth of july, the first beans popped on the 6th, and all but 2 by the 8th. I have 11 little sprouts that will be ready to recieve nutes soon. I want to get this figured out pretty quick, so I can fix the situation before it is a problem for my babies. Thanks for any input. Will add rep for advise.

i would definatley go back and return for the hydro. soil already has ferts in it and really is completely diff then hydro. so just to be safe use the right stuff for your girls.

Ya, that is what I was thinking also. Thanks for replying seems more people like to read, then reply. They were closed today, so I will have to do it tomorrow.

no prob man . tho theres also a lot of people who may not no about that certain subject, and some that dont feel like their two cents will do anything. so hows it goin now?

You shouldn't need nutes for atleast two weeks the plant should have enought nutrients stored in them to buy yah a couple. But i would say go for the hydro i had alot of trouble with nutes i had to play the guessing game for 4 weeks b/c i didn't know what i was doing and stunted 3 plants. If your not sure i would just add a little bit at a time.

Yes, you need the Grow Big for Hydro... You might as well buy the three pack because you need them all, probably wouldn't hurt to get the three solubles as well.

You will also want to make sure you have PH up on hand, as the Fox Farm really drops the pH at the end of season.
