I don't see why not the both have the same pH requirements, I would aim for 6.0 but if it fluctuates a little either way (5.5-6.5) not a problem.

I just wanted to elaborate on this. Yes pH is the same, but there is a difference in
nutrients. Tomato are a continuously fruiting plant, and spinach is not. Therefore tomato's would do better with a continuously fruiting nutrient formula, and spinach would do better with a vegetative formula. If you were growing on a commercial level, or just really wanted to have the best formula for the particular plants, I would say they should have different reservoirs. But if it were me and resources may not provide what I wanted. I would go with a continuously fruiting formula for the tomato's. The spinach will still grow , be good and editable. But they may want to flower and seed, rather than focusing on growing foliage.
