Outdoor Grapefruit but inside, sue me

Measurements we're took on 2021-01-24. The end of the week was full of stress for the lady. She got topped on the 28th and transplanted the next day. We should start LST and low dose nutrients next week. The new soil is the HollandBasics available on amazon and I gotta say that's it's pretty light, packed with perlite and seems to be very good quality in general.
