Basil, lettuce, kale, chard, parsley, cilantro will all do fine around 700-800ppm (thats everything I run in my NFT system).
Tomatoes would be fine for a little while, but once they get 8-12" they're going to need much more.
If you gave the first group of plants tomato nutes (1400-1800ppm), they'd burn out in a few days.
Lighting is also different for both, but not sure that matters if you're outdoors.
