Was about to buy a few hundred worth of Flora series, and was thinking maybe powdered is better, and not paying for water being shipped across country. I like that Flora series in coco, has charts that tune for every single week of growth through flower. Anyone using Jacks that could point me in right direction? I filled out their form and never heard back from them, so thinking maybe the GH Flora series is better and they do not have a product line that compares.
