They look like they still need some time. Your best indicator for ripeness will be by looking at the trichomes on the bud. General recommendations are to harvest when the trichomes are 10% amber, 80% milky and 10% clear. This is a guideline, not a rule. Over the course of a few harvests you will determine your own preference. More amber = more couch lock. More clear = more cerebral high. You do always want to have the majority of your trichomes milky, in addition to the above mentioned preferences.
