Second: Eliminate the accelerator. This is most likely the culprit. The accelerator is probably introducing moisture into your finish. The CA doesn't like moisture and if you apply the next coat of CA before it dries, you're screwed.
I have a slightly different rationale for this same suggestion. I'm by no means an expert on these things, but I didn't think the Accelerator would add moisture (it will cause white spots, so that may be moisture, but could be other issues also...), but I've had problems between layers when using accelerator if you use too much or go too fast. Using too much or using it on too thick of a coat of CA will cause it to turn white, I think from the accelerator causing it to cure/react too fast (try it on a small drop of thin CA on some useless material and you'll see a bubbling, smoking, not pretty finish material...) Also, if you put too much accelerator on the last layer and it has not dried/evaporated before you apply the next layer, the accelerator will react with the new layer CA before it has a chance to adhere to the previous layer, and what you have then is something akin to having 2 separate pieces of plexiglass pressed together, it looks clear, smooth, and transparent, but it's not a single piece...
My experience, assumptions, and understanding of what's going on, take it for what it's worth, but I use Medium for my CA finishes, and find that if I resist the temptation to put too much on, it dries pretty quickly by itself, not much longer than it takes to be sure that the accelerator is gone...
