Burmeseanswered grow question 4 years ago Hi Bro...When I look into your comments, your soil mix contains bone meal. I think that’s the smell of bone meal.I always get that kind of of smell from my soil after I topped my soil with bone meal.When bone meal is wet, the odour is unpleasant.As long as your plant doesn’t show any other symptoms, you are good.Happy growing.. ✌️
