strange pigmentation during air curing process

[Abuzer]

Hi Folks,

This growing season is somehow strange and I recognized something I have never seen before on my air curing Virginia leaf.
It should not be mold, but seems to be trouble while curing to change color.

If you have any advice or know the reason for this anormally Id be happy.

I am planning on air curing my tobacco and later on pressing plugs or navy periques with it for my pipe.

I have often this type of discoloration.
If I remember well, it happens when the temperature is low.

I sometimes get as well. It seems to sort itself out. I think it's caused by the leaves cooling down and the curing process stopping at that point. As the day warms again they carry on curing. I've only had on sun curing leaves. Don't worry, she'll be right.
