I don't know what help I can be. All i can tell you is I can't ever remember having a plant die on me. Not that i'm an experieced grower, but i've had a few grows, not with great yields but a plant has never died. I'm not saying a half decent grower would never lose a plant, i'm sure even experienced growers lose plants but they're probably dealing with a lot more plants and more complex systems that may suffer from mechanical failure. You should read through the growing faq, skinky attics noob guide to growing dankness and maybe some growlogs to get an understanding of what growing is about.
