Your lady needs veg nutes atleast until she starts to stretch. Than u can go to a well balanced transition feed. Start using bud ignitor ect if ur going that route. Bit still than make sure it's even balanced. There is still a large demand for nitrogen when shes stretching and throwing off rampant growth preparing for full bloom. Happy growing and stay lit fam.
yo creo que la llevas un poco con retraso en crecimiento y tiempo,en teoria 3,4 o 5 semana como mucho florean solas,espera una semana más ya veras como empieza a mostrar signos de preflor,saludos
