Outdoor Grapefruit but inside, sue me

Measurements took on 2021-02-14 Another smooth week. I started giving her nutrient this week since the organic part has already been disrupted by the calmag last week. Gave her 3L of solution. I also lollipoped her removing lower bud sites and some fan leaves. 2021-02-14: First haircut today for the lady, she's beautiful and breathing easily now. I forgot to take a before-after shot though. I also rearranged the LST set-up for better light exposure. I gave her water yesterday and measured the runoff's pH at 5.5 so I'll be giving her a higher pH water for the next time. That was probably the cause of the problem last week. 2021-02-15: Nothing to read. 2021-02-16: Nothing to read. I gave her 7.8pH water to correct the acidic soil I had last day but the runoff was still at 5.8. She doesn't show any signs of deficiency anymore though. 2021-02-17: Bud sites seems to turn yellow. Since I already ruined the organic part, I think I'll actually start feeding her tomorrow for better results. 2021-02-18: First feeding for the lady. I went with advanced nutrients 3 parts base nutrient and gave her 3L of solution with 12ml of each compound. 2021-02-19: Colors are getting lighter. 2021-02-20: nothing to read.
