This week, I let her grow on her own and stretch significantly (~1-2 cm per day).
Still having issues with pH and possibly too many nutrients in the soil, but she’s handling it well.
Day 45:
Watering: 3 liters (pH 5.7; 1400 µS/cm)
Drain: 0.5 liters (pH 7.0; 2000 µS/cm)
Day 48:
Watering: 3 liters (pH 5.1; 1600 µS/cm)
Drain: 0.3 liters (pH 7.1; 2200 µS/cm)
