She just keeps on trucking. So far absolutely no signs of any deficiency or burn and still just adding plain water. I'm pleased with the rate of growth too considering it's not getting 18-24 hours of light like autos typically do. Definitely want to give the next batch a go with topping/FIMing since I believe it will handle it ok. Gonna stick with LST for GSC1 as a control so I have a good idea when it will flip.
Have had a few days of decent rain so it's saved me from watering much this week.
** Growth after my FIM attempt on GSC2 is returning. Hard to tell what my results will be on that one. GSC3 is a little behind the pace of GSC1, little smaller and not showing prepistols yet. Might take a little longer.
