Q. Queen Palm Problem

As new leaves form, a white, pale tint seems to come from inside the leaves. Where fronds separate from the trunk, it becomes web-like and dead. Untreated this whiteness grows up the frond until it is dead. Palm frond weakens at the base and can grow warped off to one side. Is it a pest or disease? Can it be treated? My location is Houston, Texas.

Q. our queen palm keeps losing leaves ~ faster than the new growth.

There is a white substance coating the leaf stalks quite heavily on some.  The candles on one have died and also the berries have died. They were planted in the spring and seem to be declining. There is some new growth but as soon as we cut off a dead leaf, another starts to yellow and then turn brown.

It sounds like a pest. There are a few it could be and those are scale, spider mites and mealy bugs. These articles will help you determine which it is:

Neem oil will help in treating the pest, regardless of which one it it. Here is more info: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm

This article will help. The article is about Sago Palms, but the same principles apply to Queen Palms as well:

Q. How to get rid of cut worms in a tall Queen Palm

You can buy a substance called Bt (short for bacillus thuringiensis). It is sold at many garden nurseries. It is a natural bacteria that kills caterpillars of all kinds. This should help eliminate them.

You can also use neem oil. It is not a quick kill pesticide, but causes the caterpillars to stop eating and they starve to death. The nice thing about neem oil is the tree absorbs it, so even if the worms can burrowed into the tree, the neem oil will still reach them and kill them.

Both of these substances are harmless to people and pets.

You might want to consult a professional exterminator to determine what kind of ants they are, and how to treat them. If you want to try a home remedy, this article will help you: https://www.gardeningknowhow.com/plant-problems/pests/insects/home-remedies-carpenter-ants.htm

You need to fertilize once a season in spring, summer and fall (skip winter) with a fertilizer that has an NPK of 8-2-12 as well as containing some magnesium. They do sell special palm fertilizer that can make things easier.
