how long 'til blooms open?

[escualida]

Hi all, I don't have much experience with Dens but I have a Den. Christy Dawn that has the beginnings of some flower buds (I think) and I was wondering how long does it generally take from this stage until the flowers bloom?

Also, I was told to give this plant a sort of winter rest where I should water less often and not fertilize, if these are buds do I still do this?

Also, it has a keiki growing out of one of the older canes... is that bad?
