I'm new to this whole process, My first jar had a very weak flush and when the next 2 were ready, I dunked them all at the same time, there appears to be a lot of white fuzz on the cakes a few days later ..is that normal?
i would think it is as this is the fruiting process now and t is growing the base for which the pins will pop out
"white fuzz" is to general for anyone to give you a reasonable answer, be more descriptive or better yet upload some pics.
