from those pics i say you have at least a week or 2 left. got any full plant shots? it's real hard to judge when a plant is finished by pics. at least it is for me. i look at trichs, but that is not the only thing i go by. look for the calyxs to swell, pistils to die, leaves to yellow, and i also found that in the final days of flower that the buds start to look "knobby" .
