We saw no visible budding of the plants. The pH of the water rose from 6.1 to 7.0 from Monday at 12 pm to Wednesday at 9:50 am. We added 1 teaspoon of the pH down power again and brought it down to 6.1. Two Hours later we checked the pH again before we left for spring break and the pH was at 3.2. We are keeping it that low because of being away for the next week, and having rock wool as a support of the plants it absorbs the pH of the water and raises quickly.
