Yes, Experience is important, but if you have not done your research you can have all the experience in the world at doing it the wrong way and be knocking on a brick wall.. And when you say something like "expect more things to go WRONG than RIGHT. Pump failures, leaks, feeding tubes clog, Plants get sick, and diseases spread like wildfire through the reservoir..and you wont even know it until it's too late!" I just have to smh and say your biggest failure is yourself and your under-preperation and lack of knowing what your doing by not talking to fellow hydro growers. I have had not one of those problems stated unless you consider nute burn sick plants... which is really not a problem when flushing is so effective in hydro. I'm just telling you now, I NEVER grew indoors period before I started 2 years ago with hydro, gave myself 2 months of research and preperation and dropped jaws of my circles organic growers.... sorry you have had so many problems but I'm telling you, in this case, if you don't have the knowledge first before you gain the experience, your setting yourself up for failure.
