There are no nutrients being fed yet, however Lemon Pie is showing very early signs of being 'hungry' without any evident deficiencies.
I reckon a Trellis Net will be put in place at the start of the fourth week of veg (Day 21).
In the coming days I'll be considering starting some LST techniques to get the nodes going in the right direction for the makeshift net, and the extra soil is planned for the 5th or 6th week, unless I come across issues.
