pistils changing colour too early ???

Harbinger of harvest - pistils seem still growing , looks like the stretch is over , it's hard to say as only recently I've changed tent 4 a bigger one and defoliate her heavly 2day , added 4 litters of bottled water , as didn't had any dechlorinated , what ppm level would you recommend ? I'm using an as that is my first grow , and pH perfect sounded very appealing

Your seeing Nitrogen Curling and dark colors on the foliage and on the sugar leaves.. This is saying the plant is able to intake too much nitrogen..

Doesn't look too bad yet.. Is it slowing down like the bud production? or still stretching? like is it growing still?
