Are those outdoors? You posted this in the Indoor section... :wtf:

Looks to me like they are in the beginning stages of flowering. I only grow indica strains, but mine usually look like that at about 2 weeks in, meaning you probably have a couple months left at least if they are sativa.

If you cut them now, you will have next to nothing for a yield. The buds lose a lot of mass during the drying process, and from the looks of your pics, you will end up with sticks and a couple puny calyxes per bud site if you harvest at this point. Wait it out for several more weeks, you will be much more satisfied. :thumbsup:
