Hello was wondering if anyone could give me some advice as ive never reversed anything as of yet. Think i have my head round making solution but what Im stumped on is that I only use auto's and been reading people spray before flowering but if your using reg seeds how do you know its not just a male? Do you wait for pre flowers? Or can you use femmed seeds to start with? I heard you cant reverse femmed plants but I have no idea. Many thanks.
