the grow big is for veg. and the tiger bloom is for flower. the big bloom is basically a soil conditioner and used during veg. and flower.
the additional additives i also use are the open sesame,beastie blooms, and cha ching.
i start out with like 1/4 strength and work my way up to around 1/2 strength and use nutes every other watering and plain water every other watering. if i start to see the leaf tips start to brown i cut back the nutes to every 3rd or 4th watering depending on what the plant needs. just by looking at the color of the plant, you can tell if its hungry or not.
i also use sunshine mix for the growing medium.
here is the soil feed chart but i have never needed to go full strength on the nutes but i use both the liquid and the solubles together.
