Viral infection may not show right away, or even at all, but can be passed.... their behavior can be complex and hard to track,... Commercial bud is a common culprit, they will not ditch the plant out of $$ concerns, they don't give fuck-all basically as long as they get paid! And yes, viral infections can be passed into the seed, since the virus genome is integrated into the cell's DNA already... this is why it can never be "cured"....
Like I said, this is my opinion, visual ID is not good enough usually to confirm it, but it sure looks very suspect... Your call!
