Heat them hotter. - 120°?
I did not mark the jars so no idea if its the first one or two. I will have to do that. I have noticed also though that when i mix flavored honey and dispense out of a normal bucket and gate valve, I have had one or two turn quick as well and the rest are still fine.I have noticed that when liquifying crystalized honey(I also heat to about 105°),there is always a small amount that remains crystalized and settles to the bottom.For this reason,I try not to bottle in advance as that small layer of crystals detracts from the appearance and rarely can be "heated out").
On to your problem.Is the crystalized jar the first one poured?
I suspect that when you heat the honey,any crystals settle to the bottom and if your outlet is low on the bucket, they will flow into the first jar and act as seed.
Or, as Roland suggests,if you have a Maxant NoDrip valve,there may be a "slug" of crystals in there.I believe there is another recent thread cocerning a crystalized valve.
As for the "floaters", don't worry about it.Just pay attention to the level of the honey and don't let it get below the top of the outlet.Near the end you can prop the bottler on a 2x4 overnight so that the honey settles at an angle over the outlet.Use that last bit that remains for personal use or family give aways. It's just air bubbles and minute bits of wax if the honey has been strained previosly.
