Re-use soil? (Ffof)

Hey so I'm currently on my first grow just trying to gain experience atm using bagseed, I've done alot of research on how to "identify" a plants gender by the seed but I've came to dead ends but I'd hate to waste money on raising a male for a month unwillingly, so I was wondering if I grew a male until it shown its sex would i be able chop it/pull it out the soil and re-use the soil again for another plant? I use FFOF (Fox Farm Ocean Forest)

Heck yes. I reuse soil a lot.

Reusing soil can be beneficial actually. Everytime I reuse, I amend with goodies and top dress. Never had a problem.

Both good answers I do the same

Thanks for the information guys, do you think just adding maybe just extra worm castings maybe like 15/85 and topdressing with worm castings (Dr Verms Worm Castings is what I've ordered) as well would be enough ?
