You had WAY to much ferts and your plant was more stressed than a hooker in church...YOu should of went half n half using the MG and Regular Plain Dirt As Stinky suggested, Soaking for 15mins in water could have shocked the plants enough...SO your plant was shocked, stressed, and over ferted!! Plus you were growing outdoors and tried to bring it in doors, and thats what probably set it off, but you were better off leaving it outdoors to finish up....I feel your pain but we learn from mistakes, trust me, i did..... Good Luck on the next grow and don't give up
