I took the plugs and put them in the Hydroton about level with the plug. They've been in the system since day 4 and I've been giving them about a 33% nute solution (technaflora products) all seems fine...
Plants should have no nutes the first two weeks, then 1/4 strength for a week, then half, then full to be safe. But if everything is fine, I guess you don't need to worry about it.

I have the light on 24/7, when do I switch to 18/6?
Now. Plants take in the stuff they need during light hours, and process the stuff during dark hours. They need both unless you are rooting cuttings. I have only two light schedules. 18/6 and 12/12. People may say different, but I don't think adjusting those schedules will do much of anything.

I don't have a dripper tip in the end of my tubing for each plant, it gently flows out of it right now, no splashing or anything like that, is this ok?
That's fine. There will be plenty of splashing from your air stone and res. pump. But it should be more like dripping instead of flowing.

I've been feeding every 4 hours for 5 minutes. How will that change once I start the lights on 18/6?
Feeding schedules on systems like yours are very debatable, and as varied as the systems are. You just need to keep one thing in mind; you want your roots to get as much oxygen as possible without stressing the plants. This means that you actually want your roots as dry as possible. Believe me this is the key. Light schedule will not matter, just make sure the roots don't completley dry out, but are as dry as possible. I have a hybrid spray/dwc type thingee, and I water for 30 seconds every 10 minutes. For the most part this is pretty typical.

I've read that I can water every 3 hours for 4 minutes but when it comes to using Hydroton, everyone seems to say something different when it comes to a feeding schedule.
You need to remember that there are many growing mediums, and all require different care and schedules. For example rocwool holds way too much moisture in my opinion, so I would water much less often in that than I would clay pellets (Hydroton is a brand). Bleah, I hate rockwool. Way too easy to get root rot, mold, etc.

Hope that helps a little.

After reading about growing for the last 10 years or so, i decided to give it a shot. I spent the last 3 weeks in this forum reading everything I could (THANK YOU ALL), decided what would be best for me and went to the store. The guy talked me in to a few changes but I came out happy and spent a exactly what I wanted to.
