Once there are 98-99% brown pistils/hairs, you will be entering the harvest zone.
Need better pictures and pictures of entire buds, not just random trichome pictures.
56 days for JH would be unusually early.
Most of them are quite clear still. Only a few scattered milky trichomes.
Give her another week and check in on them. If light amber colors start to appear, think about flushing / harvest! :)
