It seems that the nutrients I gave them helped and they look happier. Still watering every 3rd day +-300ml each and once a week with nutrients. Main-lining them to get the maximum of my grow tent. The smell gets quite intense after a while without opening the window, so I started using a carbon filter. I am happy with how they react to my training.
Happy growing guys
@Swoky, hi, I don´t know. I haven't been using anything else. I'm watering them every 3-4 days. Last grow when she was blooming it was every 2 days. It really helps to air the soil, so it doesn't get too dense. Good luck for you too
