One plant had lots of bud and the other female is not budding

Why is one plant having tons of buds and the other one is a female and is just not budding it is a hydropnic setup the are getting the same nutrients under the same lights just one is budding like crazy and the other one is not!!

pics? Are they the same strain?

pics would help and if they are the same age and strain then one might be make or hermy.
