I'm going to agree with people here about the harvest being too early. I know your plants looked like they were about ready, but there is a lot of pistils still growing on the plants when I looked at the photos. If you see those white hairs, the plant still maturing. Means it's not ready to harvest yet. Some strains are different than others. Second, when you dry and hang your buds, make sure you have a humidifier and a way to check humidity. I dry mine in a dark sealed closet, humidity between 55-60 and with my carbon filter circulating air. You can just use a small fan. You might be able to save your harvest by using orange peel in the jars of the weed is too dry. You see, the problem is that when weed dries too fast, the chlorophyll cannot escape and... Well, then you're stuck with the grass/hay smell because it's now locked inside the bud. So that said, I wish you luck on your next grow.
