If you haven't turned your clones you can use Reverse on them to prevent hermies....I use it and have not had a single hermie since....and I always have at least one light issue per 12/12. This stuff works great.

Ps...it's pretty normal for light leaks to cause a hermie issue so I wouldn't be too concerned about the clones. If your plant hermied for no real reason I might feel differently...capice?
