My first ever grow/auto

A very good week for the plant but a very sad week for me. Not plant related but still big events of my life during this week 4, a close friend passed away and I got covid for the first time. I added a few pics to remind me what has happened this week. Rest easy my brother. Anyway, she got her first LST and I think I did very well on that. Had to moved out of the house since I didnt wanna spread covid to my parents. Came back home 5 days later and I was surprised how big and fast she grew. However, I let my brother feed my plant and he doesnt know much about ph so he gave her a cup of bottle water everyday for 5 days (ph about 7.1-7.4). Seems to effect the leaves abit. Fed her Cal mag and Silica for the first time (separately, separate day). Good thing I didnt give up on her. Feeling motivated again
