Try using a balanced nute for Veg 20/20/20 or something thats high N and lower P&K, but not too low in P & K. A Lot of growers tend to give there plants high N nutes eg 20/2/5 or something similar. Plants will need P&K as well during veg, just less of it.
Once your plants start flowering, switch to High P&K nutes eg 1/14/15. There are a lot more to nutes, but you'll have to give more cetails on how you planning on growing.
Personally, I prefer Oraganic nutes. Makes all the difference in taste in the end.
