These autos have been growing quite rapidly in the past week. I've given them the stage 1 feeding from Robert's nutrition line, 1/2 tsp per L. I've only given them a little bit as I'm aware that their root systems are still development and don't want to overwater. But i consistently check soil temps, pH of water and soil, as well as ppms and ECs. Looking forward to seeing more development on these ladies, this coming week
