Hello. This is the end of week 8 and the beginning of week 9 of flowering. This is the start of flushing for these lovely plants. I'll flower these plants to 10 weeks. I also like a few days of dark just before harvest. There's still food left in the medium, so the plants won't starve. I've found measuring the runoff that the first flush is around 750 ppm and the second flush is around 450 ppm and the third flush is around 250 ppm. The plants use up most of the food in the pots and have pulled alot from their leaves. Then it's time to harvest the very clean buds. There is no chemical taste if you flush and you get nice white ash when smoked. I got to say - look at the differences in the plants, wow, looks like 4 different strains. They all smell similar but look quite different. That is a common question on the questions page, why do my plants look so different from the same strain. Keep growing straight. Chuck.
