Tropicals & Tender Perennials: My 1st bloom since finding out what it truly is!, 1 by Gitagal

The plant itself, before it blooms, is actually quite ugly.
This is the plant with blooms #3 and#4 in the above post. The "spectacular" one.

The fronds have gray, calloused tops (bottoms are normal green) and very one-sided.
It is hard to even water it--as it tends to just run off.
I do not fertilize these a whole lot--just kind of let then do their own thing.
Should I fertilize? With what?

They also get a semi-dormancy in the house all "winter", which we did not really have this year.

Can any of you tell me why the tops of the older fronds look like this?
Does not seem to affect the plant any.

#1--the whole plant--YUK!
#2--Showing some of the gray, calloused tops to the fronds. What causes this?
#3--This is the top of one of the older fronds just as it is growing out of the pot. Ugly! Cracked!
Yet it supports all the lower growth and bloom buds.

Any comments are welcome. Thanks, Gita
