I have 7 plants indoors in pots, with 60w full spectrum lighting. All of the plants are feminized.Auto flowering. Planted late around July 1st
3 plants are doing great, about 3 feet tall and loaded with flowers. The other 4 plants look healthy but no flowers at all. 1 of the 4 is a 4 ft tall “Girl Scout Cookie” , looks great but still no flowers even after reducing the light to 12 hours on 12 off.
Is that powdery mildew on your leaves. Also you should have about 450 watts for that size of space. So you are way low. I’m not sure if that is contributing to your flower problem or not, but I would add more lighting.
Also I noticed some canoeing with your leaves which suggests overwatering.all of them autos? Did you do some topping or filming ? I saw a stem or two with nothing on them .thanks and happy growing I would also take what max said in consideration.
