My plant is growing silver hairs out of the leaf..

Last night I was looking at my oldest gurl...a little over a month now, and I noticed what looked like a small shread of paper sticking up off a leaf...then when i went to pull it off it snapped in half and realized it was connected to it and it was silver..THEN this morning when I was looking at it again I noticed another one it looks like someone just laid the skinniest smallest piece of tin foil down right in the center of my leaf, about a centimeter long not wide at all...anyone know what the hell it is????
