URGENT! What is this!?

[2palm]

My palm was fine a 2 days ago but now this is suddenly happened. It’s only affected two of the leaves so far but it is really concerning. This one is kind of a brown with white haze all over it, and the other one is sagging very low down to the ground and bent. It was normal literally yesterday and this is all very random. Do you know what this is? how can I help it? I really don’t want this to die. I’ve owned it for three years and I love it to death!

Oldest leaves are fading away. Trim them off when they turn brown. The rest of your Washingtonia palm looks fine.

That makes sense, but I am still concerned about frond in the first picture. It’s a weird like purpleish brown on some of the tips and the rest of it is a dark green. Thanks for the advice though.

At first glance it looks like over watering.  I'm not 100% sure though.

I would think that this could be a possibility, also remove the rocks so that the surface roots can breathe properly, if overwatering this could also be further exacerbating the problem. Roots need oxygen not big rocks stifling their air flow, if you need to use rocks to weight the pots from high winds (I do) put them at the bottom of your pots and they will provide more drainage and increase oxygen flow instead of decreasing oxygen to the root zone.

Wouldn't harm to drill some more drainage holes in the bottom of that container.

They’ll literally grow out of small cracks in concrete and asphalt. No need to remove the rocks. Also, when I owned multiple acres in San Martin, CA, I had several Washingtonia growing at water’s edge (big spring fed pond) in black sticky wet heavy clay soil year round and they loved it. These palms are nearly indestructible and nearly maintenance free in the right climate. Potted specimens require a little more care since their roots are restricted by the pot but are still one of the easiest palms to grow. Just trim off the old fronds when they brown. Your palm looks healthy.

It does look pretty common for Washingtonias in pots.  From what I've seen, they would much prefer to be planted in the ground.  Less leeway for error in a potted situation.

Here is a demonstration that they can grow EVERYWHERE (at least in my climate obviously) This washie is growing on rock, with just a small gap. It is growing in a torrent, when it rains all the water runs in this canal, so they flooded regularly and are growing in concrete, that's what I call a bulletproof palm. I'm Not a washingtonia fan, (I don't have any in my property)  Don't worry too much, This palm is strong.

Some of the places they manage to grow out of are pretty incredible.  There was about a half inch gap between the sidewalk and the street down at the lake and there was one growing like this out of that small crack a few years ago.
