First indoor grow! Big bud auto

Hi everyone. This is my first indoor growing and my first diary too! I’ll start from week 7 ‘cause I didn’t want to make a diary at first but now I changed my mind. I’ll make a quick resume of what happened during previous weeks: so I got these 2 big bud seeds and I thought it was a great idea to run them simultaneously on 16 L pot under one TS 1000 in a 60 x 60 grow box. The first weeks the plant grew a bit slow (no root stimulator, cal-mag, pH control ecc...) but when I started feeding them Bio grow and Bio bloom they started to push a lot, especially Gon. Killua had a little root problem (due to my stupidity) and his roots went out from the bottom of the pot and I mean a lot out, I couldn’t put it inside the pot again so I had to break them to prevent the rot of all the roots. Other than that I think the plant are growing well. I didn’t use any technique (except some little defoliation) as I am a newbie and I wanted to take the grow as safe as possible for me. On week 5 Gon started to push really hard and I realized it was “blocking” Killua so I decided to try to move Killua outdoor and for now it’s doing good. That’s all, hope you enjoy my grow and good grow to everyone is reading 🙏🏻
