She was growing so well I felt confidant topping her even before the third week, She barely blinked, then I accidentally broke a main branch, effectively destroying 25% of my plant. Such a shame. I was hoping this will be a great grow. It'll effect the yield for sure, but I think she's still going to be big. She's drinking a liter every second or third day, with very little nutrients. In week three I will start proper feeding and include cal-mag from the beginning.
