Update week 5: she will be a compact plant but she will have many quality colas for sure. She is growing very vigorously while not stretching vertically. I have to keep leaf tucking and stem displacing as she is a bit stubborn! No calmag deficiency since I have been supplementing hard. I have been watering 4 times a day.
@Chilipadi, it is not foil since that can create hotspots. It is plastified aluminium which distributes the light more evenly (just got it from some nuts package). It gets light to the lower portion of the plant.
