RQS Purple Queen

I started the flushing this week. I made an overwatering problem on her. Some leaves have like the overwatering and pH problem. Or simply, def sign. I read some diaries, air pot users have no overwatering problem even in the flushing with a big amount of water. Of course, they are good skill growers. The colour of trichomes is almost milky at top of big colas. At bottom of the colas, there is still much clear colour. I wish next weekend I can see the umber coloured trichomes and cut her. The colour of the leaves is not purple. I can see some red colours on the bottom side of the leaves. As far as I understand, the big temperature gap between day and night time makes good autumn colour leaves. It is impossible in my grow tent at summer time. By the way, my queen still has green leaves. Log: July 29: Flushing, using more than 20 l tap water directly. After using tap water, using 10 l pH adjusted water to flush again. August 2: Watering 3 l
