Have 5 Low Ryder and 6 Gorilla Glue, all AF, all same age, all same conditions. One Gorilla Glue, looks more photo that auto, has preflowered and stalled there. Lights are 24/7. All others have flowered and are stacking except this odd girl.
Did notice in general that Gorilla Glue Autos seem slow to flower, Ryders were showing pistils 7-10 days before Gorillas.
