Gave them water on Wednesday at 6.4ph distilled water. Began having issues with ac in my house. Temps got up to 81° and humidity rose to 60%. Been sitting around 75° and 50% humidity. On sunday they were ready for water again. My wife changed out the fish tank water on saturday, so i used 20% ratio of old tank water to distilled water and adjusted ph to 6.1. They are starting to take off and develop nodes quickly, now.
