I had two autos, Northern Lights. Both grew, one was more of a bonsai plant, never got over a foot tall but flowered and gave me a whopping 1/4 oz after harvest. The other grew and grew and grew, got over 3 feet tall, and not one flower at all. Not one. Same breeder, same grow space, same water, same nutes. Same everything. Your plants look good just be patient, plants can't read a calendar, they'll flower when they are ready.
