I planted 4 tomato plants later in the season (mid June?). I have a 12" raised bed with good soil in it and they get about 10 hours of direct sunlight every day. I water them every other day with about half a gallon of water on each plant through a drip system. Usually by the end of the second day they are starting to droop a little and the soil is pretty dried out. All of the plants have multiple green tomatoes on them but it seems like they have stopped developing for the last few weeks. Minor changes in size and almost no change in color. About a week ago I tried fertilizing with some 4-6-3 fertilizer after talking to my local nursery but haven't seen any drastic changes.
Based on what I have said above - am I doing anything wrong or is this a normal part of the process? Should I use more of my Fertilizer?

I used the "Fertilizer Tea" method from the bag so I took a cup of fertilizer and mixed it with a gallon of water and split that between two plants. Below are some pictures of the fertilizer I used and the instructions that came on the bag:
