top cola looks fairly ripe, but you need to use some magnification and check out trichomes. personal preference as to how much amber you want to see. more amber = more sedative effects, but the top of the plant is ahead of the lower parts as far as ripening time. Obviously focus on the bulk, but sometimes that means letting the top colas get a bit more amber than the rest.
trichomes on calyxes only, not leaves.
