yeah, it's more than safe. you have tons of initial axillary growth too. Make sure it all gets exposed to direct light and they'll take off. May want to remove 1-2 leaves at top afterward, if they are heavily shaded below.
The moment they all even up (bend dominant growth down and others catch up), you can easily send it to bloom with 4-8 strong colas. if indica, may bush out more / need more management.
