Zambeza Pineapple Express

1L bottles: 1.6 ml/L = ~1.6 EC 5L jugs: 2.8 ml/L = ~1.6 EC My tap water EC has not changed, it's not the temperature, my probes are calibrated etc. etc. I need about twice as much to reach same EC as 1L bottles. instead of being economic it cost me more to use big jugs. I can accept concentration differences but this is just weird 50% strength. if I was a noob feeding the recommended 1.6 ml/L I would be lookin at a deficient grow from the get-go. These jugs barely reach 0.9 EC or so at recommended max dose Otherwise its good stuff MORE IMPORTANTLY Plagron coco is a great product keep up the quality Plagron. But with the liquids: such a difference is unacceptable 😶
