I'd remove the paper towel (collects bacteria and molds) and let the wound dry and heal. Should be fine, but she might be a slower grower for a while.
If keeping the shoot for clone, veg it under an 18/6 lighting schedule (or so) and raise the lights a tad. (for clone only)

Perhaps a Swiffer Duster would be a better idea in the future. :thumbsup:
