Update week 6: she is growing so fast. I have been removing between 6 and 10 leaves per day but she does not hold back at all. She is taking all the nutrients with no problem. This is a great plant for sure. Compact and fast growing.
@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.
