The grower needs to develop a feel for every plant and this can only come with experience.
Obviously there are other factors to consider and everyones environment is different. However OP was asking why his buds have that fresh grass smell to them and in my experience this happens when you dont let the buds dry long enough before you bag/jar them. Personally i would rather smoke buds that are too dry than too moist.
Also i suggest dry trimming over wet trimming. Next time you harvest take off the big fans but leave the small sugar leaves on and dry trim them. Ive noticed in the past when you wet trim sometimes you get that fresh grass type smell.
