Not much can be seen in the picture. However, it does seem that the plant is significantly too young. The first pre-flowers in photoperiod strains usually appear around the end of week 6 under 18/6. Under 12/12, it takes between two and four weeks. With autoflowering strains, this is typically the case after 3-4 weeks. However, with feminized seeds, it's very rare nowadays for them to turn male. What can you say about the seeds and the age?
