Boron Deficiency?

[DAVEinMB]

Noticed these hooks last night on one of my mules, is this a sign of boron deficiency?

Thanks, Dave

No, mine do the same on some fronds & not on others...

@Laaz cool, I did some searching last night and started going in a circle on possible cause haha

@Laaz some previous posts I stumbled upon discussed hooks being a sign of jubaea mixed into the cross. Are these what that is referring to?

[Laaz]

May be, my Patric hybrid gets the hooks as well.

Nothing wrong with it. Happens a lot. I have plenty of cocoids that show this periodically.
