I agree with Worth. That pH isn't out of line. My dirt in GA was that acidic, and most plants did very well there. Peppers in particular seem to like acidic soil, and tomatoes should too. (I didn't grow in un-amended soil and didn't take pH readings from what I was growing it, but I didn't try to change the pH.)

Further, while making a small alteration to the pH is doable, making a major alteration like a full point or more is a considerably more difficult task. Remember, there's all that acid soil around your grow area leaching all that highly acidic water into your tomato beds. If you're in a relatively isolated environment like raised beds, you might try it. But frankly, I don't see the point.
