Fast Purple Regular seed Pheno hunt

On day 1 the plants are looking good. I confirmed that my one cola was seeded, so I removed all visible seed pods. After this run I will do a deep cleaning to make sure there is no pollen in my grow box. The rest of my plant colas seem fine... I changed out my reservoir and adjusted the PH to 6.1. I also dimmed my light to 75% to mimic spring conditions. On day 2 I adjusted the PH of the reservoir down to 6.1. The plants are looking great besides a few fox tails from too much light. On day 3 the PH in the reservoir is 6.2. On day 4 I diluted my reservoir with plain water to lower the ppm down to 400 ppm, and I adjusted PH to 6.2 . The buds are ripening for sure and smell great! I haven't gotten any autumn colors yet even though I have dimmed my grow light and lowered my night time temps. I hope by 8 weeks the plants will have some more purple tones but if not I'm good with the flower quality thus far :). The breeder says 7-8 weeks so I'm hoping I am close to the finish line. I will continue to monitor the trichomes for ripeness. On day 5 I adjusted the reservoirs PH to 6.0. I harvested my seeded cola on Pheno #1 as it had stopped growing/ripening and would be a good tester ;) On day 6 the reservoirs PH is 6.2. On day 7 the PH is 6.0 50 % pistils have turned amber so I believe I have entered my harvest window and expect to flush and harvest soon:) very excited!
