indoor training

Guys what should i do, go with low stress , fim, top? Im confused a bit, pack seed 3 weeks old under one cfl, after 2 weeks switch to 2 bulbs, third week 4 bulbs.. so around 2 weeks to flowering im gonna put more light. Q: what fertilizer can get small one to can do the crop, if i was growing...

i have 9 cheese plants, almost 2 weeks old, in a 1.2m x 1.2m x 2m (4feet by 4 feet by 6 feet) grow tent under a 600W hps, i am wondering wether i should top/fim them when they have the required amount of nodes or train them in other ways. Would there be enough space in my grow room for my plants...
