It could be that the double blooming one has used more nutrients than it has available to it. Feeding with a light nutrient solution can help in this case.
Alternatively, I would check the leaves, carefully, for any signs of insect infestation or fungal infection. Both can cause a freak flowering, and the decline of the tree.

I have 3 babies under my huge Joshua tree . One is about 10 inches tall with many spikes. The other 2 are just a few spikes. When is it safe to transplant them in another area of the yard? And how should I do that? Thanks.
Now can be a good time. Really, any time of year is fine with this one. The best time is Autumn, but that isn't to say that it won't do well with a transplant at this time.
Just be sure to balance watering. These trees would rather a decent dry out between waterings, if you can help it. Just don't let them remain dry for long until the roots have established, and you see significant new growth.
