GHSC - Persian Pie

9/24/2022 Plain Water. pH:6.50 PPM: 240 EC: 0.293 Plants began to yellow. I decided to check the runoff, which was 7.33. After about an hour of flushing with plain tap water, the pH did not drop. My tap water was now 240ppm instead of 110ppm. I believe they have switched to well water, which, according to https://www.masterclass.com/articles/alkaline-soil, results in high soil pH. I made the decision to purchase a RO unit. Water is coming out at 10ppm, so hopefully GH Feeding will be here by EOW so I can be adding calcium back. 9/27/2022 Prepare 8L of 1/8 strength week 6 nutrients. - RO Water: 10ppm - FERRARI GOLD: 222ppm - SUPER GROWTH: 532ppm pH:5.80 PPM:764 EC:1.06
