Hi
@Selen! Innappropriate meals, under-watering, high temperatures, and a basic pH range for the whole rud led to this situation. At this point, there's not much you can do to save this crop. I've been using BioBizz for a while, and had great results using this feeding schedule: http://www.420magazine.com/gallery/data/500/Untitled124.png, you see that one has been made especially for autoflowering strains, and it has been tested & approved by me and other growers around here. Next time I'd recommend to try to stick to this feeding schedule, while giving a good watering with plain pH'd water between the feedings, and always in the right pH range for soil (~6.0-6.3). Hope this will help, keep us up-to-date and happy growing 👊
