The purple auto is flowering fast, only six weeks old and 80% of her trichomes are milky white, she might be done after only another 2 weeks or so. Gorilla glue seems to have been recovering after receiving cal/mag and her leaves arent really dying off as much anymore, shes also finally working on her flowers a bit. The purple kush is actually the slowest to flower whilst also being the shortest ( shes an indica after all, and up on a paint bucket), hoping she will still turn purple in the following weeks and she'll probably be the biggest yielder of the bunch.
Growing same strain, I believe i got the wrong seeds as they all came purple however mine is close to 3 FT with stress training and Fat Colas and nugs! There were supposed to be Auto Kryptonite
