use software or algebra next time to double check the kit recipe. Make sure you calculate the Alpha acids of the hops they gave you and adjust accordingly. Most likely they don't check AA's of the hops before they put them in the kits. The original recipe may have used hops that were 5% but they may have given you hops that were 9% which would be a huge difference.
