Too short

The plant is indeed not very big. If you count a week for germination, it's now in the sixth week. It should already have some pre-flowers, and the structure should be developed. Check out diaries of the strain. If it's only outside, that can be normal, as they take longer.

Find her a place with as many hours of sunlight as possible, 15 hours is perfect, but the minimum is 8 for the plant to progress nicely Some automatics know how to vegetate a little longer, just as some know a lot shorter, I think that this plant will only stretch for a week and by then it will go into flowering and then strech even more the week after that... in my opinion, this is perfectly fine... take a picture of the plant in a week and compare it to these pictures and you will see that it will be at least twice as big. Everything is fine here, your plant is beautiful. Happy Growing!
