Crops can blight, animals can get diseases. I don’t know much about hydroponics but I know that bacteria are a concern. What food source is the most reliable, the least likely to produce less food than expected?

and send everyone to harvest at the first sign of blight
That sounds like a good strategy until blight happens in the middle of a massive invasion.
I still do mostly corn, but with smaller fields with gaps in between. Makes it easier to take fields out of use if I don’t need them and they’d just be wasting work time, and I can ignore blight without losing too much if something else is going on.
