The lower fan leaves appear to have some yellowing and crisping at the ends. Just fed them for the first time, nutrients, but the problem existed before then. Assuming it was a deficient???
Maybe it could be a deficient because they didn't get any nutrition before. So the plant use saved nutes out of the lower leaves to feed her newer upper leaves. The lower leaves will not turn green again but this happens often and is no problem as long as you will feed them now regularly.
