Well I only have fertilizer, because of my first time growing last year I would have a random leaf yellowing then fall off. I bought some shultz 10-15-10 to try and fix it, but it didn't do any good. That was last year though. This year I only ferted once about a month and half ago with the same stuff, but I haven't done it besides that once. I force flowered one plant, and I'm sure the other two are into flowering. Three weeks apart. I obviously wont be using ferts in flower as I don't have any for that. It's miracle grow soil though, they're pretty good size for the pots they're in.
Next year I'm so going to use a whole bag of miracle grow soil for one plant in the ground. I want to start it early inside though, so I need a light!
