I am sure next time you will get better results now that you know what its missing
I use a complete,organic fertilizer which contains Boron and it has solved all the Boron deficiencies i encountered before starting to use it,although it took almost a year for a Boron deficient palm of mine to produce its first normal leaf(thats normal for palms)
As for your Goldfinger flowers,they seem either female or hermaphrodite/neutral to me. Male flowers have an ovary that makes up only 1/3 of the total flower length. Female flowers have an ovary that constitutes 2/3rd of the flower length and hermaphrodite/neutral flowers have an ovary half the total flower length.
From the above,i would be inclined to think you got hermaphrodite/neutral flowers and the first male flowers are just showing near the bell in your last picture
