Hi robguz,
I found a 50# bag of BEI's Gaviota 10-5-40 H at the feed & seed in Pahoa for <$40. I think that + some fish fertilizer soil and leaf drenches [high N] should be in the range they need.
I haven't picked it up yet, but will unless advised otherwise.
Here is a photo of the male flowers from the 1st group
I picked them and then took about an hour to unpack and setup my camera gear.
So, they were exposed to the air and some drying before the pics were taken.
They look a bit redder than the picture in the book for a Brazilian Dwarf.
