Yes, the part we are looking for is the F1 CBD:THC ratios? The same progeny as their parents? It says mixed and doesn’t go into ratios. Makes sense a self cross would be the same progeny as it’s parent for the F2’s. It also says the F2’s progeny matches their F1’s which would imply that F1’s had different ratios from the original cross.
I’ll try a test myself and see the ratios from the original cross
