It's a bit hard to tell if the white stuff is doing any harm, Linda, but your medium does appear to be one that would hold quite a bit of extra moisture. To be safe in regards to the possibility of damping-off I'd repot those babies to within an inch or less of the new container's lip, and then expose them to fan-stirred air. I grew these a couple of years ago and found that they really don't need or want a super-absorbent medium, so if you have anything handy that you can add to your re-potting mix to lighten it (let in more air and facilitate faster drying), it might be best to do so. Sharp sand, chicken grit or fine gravel would help, but if those aren't available you might try some extra Perlite.
