Started out flushing the plant this week with roughly 16L of tap water @340ppm to bring down the soil runoff ppms. I bought 4 gallons (16L) of some distilled water and mixed my flawless finish in those. The runoff after an hour of flushing slowly brought it down to around 240-270ppm. Was aiming to get under 100-50ppm but used enough water it should be flushed sufficiently. What's left should get eaten up in the next week. Definitely much lower than before. My run off in flower was about 2200ppm runoff with Nutrients and I watered with just CalMag the next two waterings, every 2 days 4L. So every week or 3 watering it got Nutrients. Watered with flawless finish one last time on day 111, day 3 of the flush. Week 7 flower day 6 Watered Day 113, run off was down to 150ppm. Buds starting to get a slight purple hue to them. The rest of the week and into next will be watering with straight distilled water at 0ppm. Looking really frosty, hairs are mostly brown and curling and almost ready to harvest.
