Royal kush auto in the cantine boyz

Hi guys 👹😘 i dont know wtf happened with this plant😂 its still bulking the bud but the yellowing start to appear too early so it has to be a nute problem but i dont figure out what kind😅 From today i start to give just water for flushing and i think the next one will be her last one, but i will see day by day. If anyone can identify or help me do the nute problem i will be extremely grateful😘😘😂 Like we says here “chi vivrá vedrá”😝 Sciaooo guyse se yaa the next week
