Finishing her stretch, still no sign of deficiencies/burns :) Last run off came back around 800PPM/6.3PH and I decided not to feed, which turned out to be a good decision. Will feed her tomorrow (day 6 of the week) with a mix focusing on bloom.
Regarding her 2 sisters, the first (#4) is still doing amazing as visible on the video :) the other one (Dorel) is slowly recovering from what seem to have been a nutrient lockout.
I am also slowly defiolating the 3 plants, starting from the lower nodes. I’m focusing on main fan leaves for now.
