I tried to do one last tie-down before this one went into flower and accidentally snapped the top. It was still barely hanging on so I hurried and taped it up and left it untied. About 2 days late it is sticking straight up like nothing ever happened. Upon inspecting it tonight I noticed this weird mark on the stalk right under where it snapped and was wondering if it due to the snap or something completely diffrent?

Which mark are you referring to, Bud?
