Just the ones plant? Could your lights be going out? Ive had my outdoor stall in early flower. I live in an occasionally nasty fogbelt. Some plants where more light sensitive maybe?
Just took a pic of the one plant but it was just 1 in a room of about 55 plants of other varieties that seemed to be the only one stalled, wasn’t sure if u heard of that happening with the strain but def is a real head scratcher
It being an auto, lights shouldn’t have any bearing on it
