Day 77 i turned off the lights at 10 pm Friday and started my ice water flush and 48 hrs of darkness. i have not done ice water flush before, the theory is that the harsh cold forces the plant to build more trichomes to better prepare for pollination its an easy thing to do and takes no extra time so why not try it the water ppm is 435 and the first round run off was 1139 ppm second round of flush 789 ppm. the reason for 2 rounds of flush is in the first flush round the nute's latch onto the water and the second washes them away. i wait 15-20 min between flushes. that's it for today's update keep your stick on the ice Day 78 not much to say really water ppm is at 435 and runoff of round one for the day is 621 i will update with round 2 in an hr. UPDATE: ok so round 2 leaves it at 521 ppm Day 79 ok ppl this is the last day before harvest no water just ice ( i know it melts but its not much water lol ) oddly after over 48 hrs in the dark i have seen no change in the color of the plant it does not matter but i was hoping lol i took some pics for your viewing pleasure
