First MAJOR screw up! HELP!

Okay so over the long weekend I experienced my first major fuck up. You live and learn I suppose.

So I left my house to go to a BBQ and didnt come back on time to turn off my light on time ( Yeah I know I need to get a timer.) I got back 2 hours late. And to my astonishment when I got back in to check on the babies, My youngest plant ( by 2 weeks) was wrapped around my hortilux bulb. SOBS...

This plant is the only plant I have tied down because of space restrictions. Well somehow it managed to come undone and went right to my light. I cant really tell how much damage will be done. I know this will impact my yield. But when I was looking at it yesterday I didnt know what I should do.

Should I just leave it alone and see if the lower buds flower properly regardless?

Can I top her?

Is there something I can give it so she can heal herself?

Not all of the top was affected which leads me to hope that some of this area will be able to flower as planned.

Ladies, Gents.... Please all advice and help will be greatly appreciated.

There are two pix of the damage. And I also added 2 pics of my other two plants.
