Aw, sorry, I'm busting your ass, please don't pout.
Worms need nutrition too. They are good for your plants because they can break down organic amendments into plant-usable forms. And they aerate the soil if you have live worms in your grow (outside or in your greenhouse). So if you're going to make a compost heap, add worms, your garden will thank you. But you still need to add NPK sources.

Here's some worm info.
