Welcome to ILGM. Seed age is almost no issue if you keep them dry and cool. Last year I germinated seeds that I know were over 40 years old and had no problems.
As you can see, there are a lot of us here that help out for new (and more experienced) growers with problems. We ALL have problems of some kind during the grows. It is just experience that makes you better as you learn the things not to do. Good luck on your grow. Tag me If you start a journal, love to watch new growers get a good start. Jerry
