Indoor HELP! I broke a plant!

[Bateyes]

So, I was taking pics of my plants when one snapped off- not completly- its still attached by several "strands", so I guess its more accurate to say its severely bent- right where the stem enters the rockwool sponge. A lot of my plants seem to be thinner and weaker right there. This is the 2nd or 3rd to do it. The other ones lived, but stopped growing when I splinted and parafilmed the "break".

Anyhow. Should I just splint and flower it (its a photo) or whack it off and dip in in rooting hormone? Cut a bunch of clones off it? Its an expensive seedbank female, "Acid", I think, and its about 18" high. Its the only one of the strain I have, so I would like to save it, but Ive never rooted or cloned before.
Whaddya think??

Take a good pic of the bend and post it up.... its hard to tell how bad the damage is via text. Also a pic of your kit may help, along with a list of running gear... may help isolate the problem with the recurring soft stems.
