What are these red lines on this palm leaf?

[PalmCode]

Hi all, I've noticed these reddish lines on the newest leaf of my Hedyscepe. On some of the vein parts.
Anyone know what's caused it? Maybe nutrient deficiency? or too much rain? The palm is otherwise growing strong and I do keep it feed well. That leaf opened 2 months ago now.

Howea species get the red line on some palms as well. It appears to be normal, has it just started to happen?

Is this part of the variegation?

I don’t think so, some plants will exhibit a red or purple in winter but that is usually due to lack of potassium in the cold.

Very cool my friend

I get this with new fronds opening in early Spring sometimes. I think you’ll find those red lines would’ve been joined in one section of the spear before it opened and had some minor damage while in this form either from cold or sun. Is the frond opening up and recurving towards the south or east? I’d suspect most likely from low angle sun on the spear surface facing north or west. Never usually a serious concern.

One of my sabal trees suddenly put out a new variegated leaf.

Thanks, that sounds like exactly what's caused it. The frond opened up and is curving to the south. Growing at elevation it gets mostly afternoon sun in late winter - early spring from the north and west,. We had some cold temperatures around that time as well. Good to know it shouldn't be a concern.

They're racing stripes. They make it go faster!

I have a golden mid vein on the leaflets of a Chambeyronia. How common is this?

Is that macrocarpa? I'm not sure how common that is, I just had a look at mine. The midveins seem mostly yellow or light green in colour.  Maybe yours stands out so much because of how dark green the leaves are?

Hi, it has been acquired as a Chambey watermelon. I doubt however that it is watermelon.  It carries in all fronds this characteristic golden mid vein and is distinguished through its robust dimensions (very thick stem bulb for its age)  and quicker growth. Here are some additional pix focusing on various fronds of this specimen.
