is this a light leak?

[bomzi]

I just got done processing (taco method) a batch of Kodak Portra and have found what looks like a light leak in the lower right hand corner of the portrait oriented shots.

I wonder if it might be caused by a gap between the film holder and the Sinar F2 ground glass.

Would someone be able to advise on this?

I've also got a major scratched film issue... too many problems!

Thanks in advance.
