Kosher Kush - DNA Genetics : Holy Smokes in 40x40x160

Progress is a bit slow. Maybe I overdid it with the light at the start? Also, the relatively well-fertilized Plagron Batmix might have been a challenge for the young plant. Some leaves were almost leathery. But there was growth. At this stage, I had 90 mg/l calcium and 30 mg/l magnesium in the water. I was still using reverse osmosis water at the time, which I lightly salted with OsmoFit and added calcium sulfate dihydrate and magnesium sulfate heptahydrate. Since I miscalculated at first, the sulfate levels were quite high in the water. That might have been a factor in the stress during this phase.
