My friend... I am sorry to say it but that plant has reached the end of its cycle.. the hairs are brown and it looks to my naked eye (without magnification) that the resin glands seem to have begun to degrade.. I would harvest and look to tweak your set-up heading into your next grow.... Just curious about your set up.. can you give us a run down of wattage... how many cfl's, distance to plants, nutes etc? A 5 month old plant in that size bucket normally has significantly more vegetation on it. But as far as the buds readiness... I would cut it rather than let it degrade any further.
