Could environmental conditions have been a factor?
Don't know, it's been a bit hot here over the weekend though.
I have had it with a tank,tried and checked everything
Changes the juice and all was good again
It was a ridiculously sweet juice and I reckon it was the sweetener or sugar getting too hot and burning the cotton
It might just be that, like I said it's a very sweet candy floss flavour.
I'll have a mess around if it happens again and try to rule out the things I can actually change.
