James,
I noticed the exact same thing on the unknown Lsu gold/peter's honey not cuttings that you sent me. I think they're just too young to tell. I started mine in the beginning of February, and the leaves are reminiscent of Lsu gold. And, I think Lsu gold is actually quite "red" for being called gold. You can kinda tell here...http://figs4fun.com/Thumbnail_LSU_Gold.html
Btw, all the cuttings you sent me survived and are thriving and are in need of a transplant soon. Hope the saratogas are treating you well :)
