Amnesia Autogrow| First Time Grow|

Looks to me u have a lockout going on at roots I want to say too much nutrients. Potting soil has enough nutrients to feed seedling for the first 2 weeks. After that I would start slow and build up. Another thing you are not supposed to feed every watering. This will cause salt build up and nut lockout. I feed water water then feed again. Just flush soil immediately with distilled or ro water pH between 6.5 and 7.0. After that give a other watering then resume nutrients. Autoflowers are not heavy feeders they don't use same amount as photoperiod far less. Hope I can help you
