Indoor Grow #2

At the start of the last week I flushed the plant with 100L (5*25L Pot) of tab water to get rid of the remaining nutrients. After flushing, I usually don't water the plant for the last week until harvest. I lowered the tab waters PH to 5 and also the temperature to 16°C at night. I did this because in my opinion this let the plant produce more Anthocyane (purple colour). At the end of this week (Day ~ 78-80) I'm going to harvest the plant.
