Hard to pinpoint if a light leak is the problem or as albitross said just genetic, many cannabis strains have the tendency to herm in late flower, it knows the end is near and is doing what ever it can to pass on its genetics. other stresses like over and under watering. genetics is everything.

I treat my girls pretty rough usually, and and washy washy with light leaks, if they herm on me they herm on me and I will know I don't want to keep them around. Again though its hard to tell if its the light that did it or some other stresser in the grow.

I would love to see some testing on a know strain that will herm and if light was the cause. I may have to do this sometime. i have one strain in my collection that was were i started growing, it likes to herm late flower sometime and others it finishes great.
