Barneys farm pineapple express auto

Bad news. I have no clue what's going on and everyone who has tried to offer help has not been able to figure it out either. Its not overwatering or the light. No feed has been added but I did foliar some calmag because the spotting is similar to a calcium issue and she's growing slow. Anyways probably going to cull her but ill see what else happens and give her a week.
