Hello again everyone, and thanks for coming to help me diagnose what I am assuming is an issue with Ph runoff. I am growing from seed in rock wool watering by hand till the plants get bigger. I just watered one plant with 315ppm 5.7ph water and the runoff was 150ppm and 6.6ph. As I am new to growing I understand I have a lot to learn, and as such I have done a lot of research but I seem to find a lot of conflicting responses or the answers are for coco. Night temps hit 19c - 20c (66 - 68 ) day temps are 23c - 24c (73 - 75 ) night humidity is around 42% and daytime humidity is 53% Why is my runoff ph so high? I am assuming a lower ppm is good as it means the plants are taking up nutrients, but how much lower should it go? Just for some extra info, I am using advanced nutrients.
