One thing I have learned is to make sure that conversion has taken place during the mashing step, I take a small sample on a white plate and look to see if its cloudy or clear if its cloudy it needs longer.
Or you can use iodine to check to see if there is any starch left.
Although the instructions say mash for 1 hour, it may more or less time.
Learn to get a good feel for what is happening when you are brewing instead of only brewing by the clock, that was my biggest lesson.
