not to disagree with advice but as a first time grower soil is more forgiving
I suggest you use canna it has coco perlite and poo poo in it
for nutrients the thing is, it doesn't really matter, just get whatever is cheap you will need way way way less veg nute than flower if growing in soil id say get a bottle of flower like 1 L and then 250ml/500ml grow
also grab a bottle of calcium magnisium
be sure to calibrate/ have the hydro store guy calibrate ur ph and ppm pens then test smth like milk/cola and record its ph/ppm so you can calibrate off that in the future, after a few years u wont really use ur ph anymore as u will know your waters ph and it will all be 2nd nature
so thats basically what you want, for seedlings you will need to get a CFL bulb from the super market, at least until they have thier 1st set of true leaves then u can use your big light(as far away as it can possibly be)
1 thing i wish someone had told me when i first started is that you need to sex ur plants right away
as soon as they are about 20cm tall top them and root those tops, now you take your CFL from before and run it 12 12 in a carboard box or whatever until they show sex, throw away the males and grow on
you will probably want to keep a mother anyway so i do suggest you look into a 30x30x60 tent and a CFL bulb in the 6500K spectrum asap, you can use that to sex your clone in the mean time
i ended up growing out 20 clones for outdoor and 3 monsters in veg waiting for them to show alternating nodes, only 1 was female DOH!
happy growing
EDIT:
this is cheapest and perfect
