You're right not to be too concerned. I don't think you've overfed, and you're not feeding any more you say so any slight overdosing is now in check. That small leaf looks a bit like light-burn and at 30cm it perhaps is a little close for this strain, but not by much - perhaps back off to 35cm (I'd not be too worried personally). She looks really nice. Leaf fingers that have some damage on them I prune. They're not doing to plant any good, and they worry me so they're gone! If more appear in their place, then I get worried, but not before.
