Looks like you are on your way.

A word of advice with a spray system like that; do what you can to prevent the spray from actually hitting the lower leaves. What you will find is actually called 'reverse foliar feeding', where you can accidentally leach nutrients out of the low leaves by running water over them. Then you will wonder what your deficiency/lockout is, but it's just overspray. I see the signs that you have something like that going on to some extent.

In other news, I got my vertical NFT system cleaned up and assembled, and got a bunch of nice pics of it to show you, with no plants so you can see the basic structure, and then... lost my camera cable!!! oops!
