Hazz. Your looking in the wrong places. Think of veggies and hydro as two separate things. You need to do the research on what nutes the veggies needs in soil and then compare to how hydro systems work. From your level I would start with some wik. Systems first. That way the mute intake is slow while you start off.
I've been growing hydroponic vegetables for about ten years. I've done flood tables, NFT, bubble buckets, wick systems, and drip irrigation.
I have the hardest times trying to grow tomatoes. I always get BER and don't know what I'm doing wrong with them. I also grew out corn this year. They came out OK, and I mean just OK. That's why I was looking for specific hydro techniques for specific vegetables.
I can grow almost any other form of vegetable with great results. It's just Tomatoes are my Achilles heel.
