if its your first time around,i would start with a simple cheap one part mix like botanicare .veg then flower.its great for the price,just remeber your going to need twice as many nutes for flowering than you would for veg so pick up 3 smaller bottles or 1 small and one big.the more experienced you get the more parts of a feeding program you learn to use and make adjustments.its just easier when you have a little more knowledge on what your doing .imop good luck.
