I myself have never had any real luck with a auto, recently someone gave me a pack of them "La Diva" strain, and 2 looked like they would be pretty good, they showed pre-flower at 33 days, and then 10 days later they turned completely yellow and started dying, so I pulled one and the roots where huge and awesomely white but both of those died, than the third one took forever to flower, she finally flowered at like day 66, and then took 9 more weeks to finish. Then the 4th one started flowering at 14 days, so I just put her outside, really it makes no sense wasting lighting on that kind of shit, and then she only grew to 9 inches tall, there was maybe a grams and a half on her. Then the last one which is still in one of my veg tents, somewhere, at the start, looked like she was going to be nice, then around day 28 she started turning yellow and and purple all over, I think she is now at day 50 and she maybe has grown a single node on each of her branches since day 28, and yeah I will probably kill her off but its just so weird to see a plant stall like that and have all the fans underneath turn purple and lots of them are pure black and the tops of the fans are all yellow or yellowish-green with crazy purple red highlights. And no its not my living soil, as i currently got 40 others fems going that are loving life in the same stuff, crazy f'n autos! Yeah, needless to say, but I will anyways, I won't ever pay for auto seeds, that's for damn sure!!!
