Some have better smell

A question from a fellow grower:

I have an issue have harvested and cured for 6 weeks. Trichomes were mostly milky. The problem is the flowers look nice and taste good but has either no smell or a plant matter smell. Cant figure out why some of them smelled so much better right after harvest then they do now. Dont know if i was premature or didnt dry and cure proper or long enough. Would appreciate any advice. Thank you

Some were harvested to early if it has a plant smell

Put the buds back in mason jars and burp them twice a day and that signature smell should be there ?
