More Leather Problems

I have two leathers side by side on the same rock they receive the same amount of intence current and strong lighting and seem to be just fine looking . However they will on a regular basis take turns in closeing up for a day or two and then come back out at full strenth for no apparent reason. I will say thou the longest I have seen one of them closed for was 4 days so with any luck you will see yours back out again soon.

 

I have about 14 diffent types of leathers and they all close up like that some times.

 

OK, here we go I will do 3-4 pics, sorry for so many posts.
Sorry it took so long, I had to switch computers.

Thanks for your input.

another angle. White is more sporatic, but brown is all the way around the bottom and has been there a few months.
