Chopped one of em (the middle one) down today - I sampled 5 different leaves and they were all cloudy trichs. Out of my samples I saw maybe a dozen or two clear. Maybe the yellowing or initial lack of N in this one caused it to mature earlier, or have a shorter lifespan - dunno. The other two are still going strong though - about 1/2 cloudy on the oldest one, and the youngest is still clear, both of them gaining weight like crazy.
