Don't feel alone...you can read all the books, but until your actually working with real plants the learning hasn't begun. Unfortunately I learn best from my mistakes to. I have to break things 3 or 4 times sometimes before it sinks in to my thick skull. I've been growing for awhile now, and still make alot of mistakes. Usually mine are caused by laziness or missed timing now and not lack of an education...but they are still mistakes. None of us can ever learn too much. Hang in there!
