A lot of times I find it harder in the flowering phase then the veg stage....Plus it also depends on the strain...Some are more fert tolerant than others...You may think it's so called "simple" right now, but there will be a day you'll run into a problem and not know where to go from there, so I would def. be reading as much as you can everyday until you get 2 or more successful grows....I promise you will learn something new in every grow!!
