First Cultivation - Random mix

So the plants grew a lot this week. A very lot. They have improved in size and better leaves colour. I cut some little branches and put a cutting on another pot. There is something that I don't understand, the old plant, that have 2 months already and are autoflowering as well, are not flowering. I don't know why they don't grow because it's been 2 months and they are auto. I still a photoperiod of 18-6. I thought they were not going to produce a thing but they grew a lot and now I have some hope on them. Anyway, they are growing a lot and I am happy with that. I guess than in a week I will force the flowering.
