ak47 help

i just started growing my first marijuana crop ak47 feminized seeds ,i dont remember where i bought the seeds but i did do research before buyin so im sure theyre good
anyways my questions are in regards to 2 things nutrients and the methgod i am using
here goes
i purchased the lowryder deluxe grow cabinet relatively small and i decided to just grow outdoors instead of indoors
i used the small tupperware container that came with the deluxe grow box and planted 3 seeds in the 1 1/2 inchg net pots with rockwool and placed this outdoors ,the seeds have sprouted ,is this setup to small?to grow a nice crop
question 2
how do i go about feeding my plants im using hydro flo nutrients how much of each 1 do i use and when i got the a and b nutrient containers for who is familiar with these nutrients
any help appreciated

1 1/2 baskets do sound to small ?
Do the nute bottles not have mix raito's on them? I am just completeing my first hydro grow and started at like 60% the recommended mix at the start then over 2 or 3 water changes boosted it up to 90% the recommended.

I found that under is way better. def. start with light water... Just a question, do you have a ppm and ph meter?

my ph meter is the strips paper strips that change color according to ph ppm meter what is that ?what does it measure?
and i just checked on my plants and they been outdoors for about 2-3weeks and they are tiny like 1to n1and half inches above the rockwool ,what do u think my prob is i can take a pic if this will help u help me please let me know thank you

oh yea and for the nutes it tells me to use 3tbsp of a to 1 tbsp of or vice versa the nute name is hydroflor or something like that if u familiar with it

PPM and PH are 23 totally different things! PH is the acidity of your water and PPM is PPM of your Soil and Nuts. Are you even checking the PH of your Water to make sure it is between IMO 5.9-6.3?
What are you using for a medium? if they are just in rockwool and outside, They are to small to be getting all that bright light! the need to be "hardened off"

Oh yeh, and if they are that small there is no reason to even be using nutes yet! You are probably gonna lock them up by giving such tender roots too much
