Hey Scott....your soil is probably fine - but - if you wanted to make sure - you could take a soil sample to your local extension office to have it tested. They will test for pH and soluble salts - plus maybe some other stuff - you'll have to check.

That test would help determine if the soil has anything chemically damaging to new plantings.

As far as I'm concerned, veggies are a big PITA because they are always getting attacked by stuff that can do damage.

Also another thought - can you rule out water relations as an issue?

Push come to shove and pending the soil test results - you could remove some of your old soil and add in some nice fresh planter soil from your local materials shop. The place that sells mulch, rock, sand, etc. Personally - I don't like what most consider topsoil or manure. What you want is something lighter in texture and consistency.

Hope this helps!
