Auto fem og kush

Hi, I am growing auto fem og kush in a grow box under 45w LED and hydro..it's day 30 and all is looking healthy but I'm not sure when it should start to bud? It's meant to finish by around day 56, will the buds be fully grown by this time? Thanks in advance...

I figured out my problem...it's a fem not an auto so didn't put it onto 12/12..however two weeks after starting 12/12 is now budding and looking good..just gonna have to be patient as was vegging for 8weeks instead of two!!
