I have a double Alexander and the newest fronds are a bit droopy. They are also a lighter green than another double Alexander I have.

It was planted late last summer. I believe it is planted at the correct depth. Back in March I fertilized it with a general palm fertilizer, as well as manganese and magnesium.

It appears to be growing at a decent clip; the spears grow at about an inch or so a day. Not really sure what could cause the droopy fronds. Only thing I could theorize is perhaps I over-fertilized?

Any help would be greatly appreciated.
