Purple Afghan Kush

Sorry for the radio silence, I had a hectic month, as well as taking way too long to get a problem correctly diagnosed. I had been experiencing serious ph issues. I went out 2 weeks ago, and bought a blue lab ph meter, and started feeding at 6.3 a week and a half ago. All but 3 are recovering nicely.. but the critical plus 2.0 is still a hurtin' unit. Based on the explosive recovery on these girls in 2 days, I have fath that she will come around quick. Although at 13 weeks it's already been an exceptionally long veg period for a tent grow, these girls have been stunted for the last 3 weeks. I'd like to see where they are in another week, and try to scrog them for another week after that, before I start to flower. Looking at the recovery on the gorilla (which was always a big plant), as well as the explosive growth on the larger purple afghan kush, I think I can bring this back, and have some really nice plants come flower time.
