I've read that it is most likely inconsistent watering. So am I
watering too much/too little. Too much at 1 time, not enough at 1

To get even watering try this:

Take a gallon plastic milk jug and poke a small hole in the bottom
with a nail. Bury it up to it's neck beside your tomato, and fill
twice a week.
