At the start of the week I cutted the lower branches and fanleafes away, that the plant can focus her energy in the main bud. I need space in my growbox for a second autoflower that will come the next days. So I can't let the plant grow in the wide. I know it's a little bit late for that, coz the plant already started to flower. But I wasn't expecting that she will start flowering before day 21. After cutting she struggled a little bit for two days, but then she keep on growing well again.
