Anyone have experience growing Black Panthers?

I was gifted some black panther seeds that are supposedly isolated.  2 plants are growing, but they look very different.
 
One has purple leaves, and the other has green:

What color leaves are normally on a black panther?  Both are right next to each other under the same set of lights, and were started at the same time.  However, the purple one almost died to a combination of aphids, nutrient burn, and overwatering.  It was down to a single cotyledon before recovering.  Not sure if that could influence the leaf color.

It would be funny if someone grew these in Vietnam.

While the seeds you received may have been isolated the originators website reports differently along with only F4/F5 purity.

So it's likely an unstable phenotype, and based on the differences I'm already seeing, I likely am growing two very different plants. Excellent! I can't wait to see how they turn out
