I just think that unless you are pretty sure this was germinated by pollen from an unknown male, you should trash can it. Consider, too, that the unknown pollen donor could be from feral hemp or a large low grade gorilla grow.
IMO, seeds are just not that expensive--so why take the chance with a real unknown. Five or ten bucks for a seed that can produce something worth $500- $1000 is not too bad in my view. Anyone with a decent indoor space has spent thousands to set it up, spends hundreds to keep it going--electricity, nutes, supplies, etc. Why scrimp when it comes to one of the most important things in your grow--good genetics?
