Auto Gsc coming week 6 still in veg. Lst adjustments every day. Soil ph is 6.3 taking a little u see half gallon ever two days. LST the main branches across to allow light to the bottom areas.
Since you asked yes do defoliate at least leaves that are laying on top of each other, could save you from any mold issues. I just leave enough fan leaves for the plant to cannibalism it’s self in final flush. However you won’t be flushing I guess, so just make sure you get light penetration and no mold.
