Certainly too much fertiliser, I reckon, K 9. Mine, in a pot, gets a feed in spring and that's it. At most, you'd only fertilise every couple of months. I don't know what your temps are like but I'd be surprised if it needed a gallon of water a week either. Mine, in full sun, with temps in the mid-30s, is only watered every couple of days.
