I've seen this mentioned a lot, harvesting too early brings on the grass smell. I've also read that most harvests smell this way, like grass, because of chlorophyll, and this is why we dry and cure buds after harvest, to break down the chlorophyll. If we still smell the cut grass it is still drying and curing. Some say this is how marijuana got the nickname "grass" in the first place.
This second idea makes sense to me and I've noticed it on my own grows. So
@Aacis after a week how do they smell?
Here's a link to an interesting thread on this same subject from ten years ago:
