Den Bud Blast HELP!!!

[Soonix]

Hi,

My Den. Sonia Earsakul is in bud, first time for me, however the buds seem to grow healthy and big. The bud is a little over 1 inch and than it starts to shrivel up and die When i inspected it it looks like its still sealed, the petals are stuck together. It has 6 more buds that are in the growing process is there anything i can do to avoid a repeat of this horror show? And is this a nature thing or something i'm doing wrong?

Thanks
