I have a 3 month old kb plant in my dresser setup and its staying pretty short and i like that but my friend originally had it and fertilzer burned it so i brought to my house and have been nursing it i topped it to keep it short and now the new leaves are coming out but i want to change the light cycle soon to check the sex of the plant but im not sure if i should wait for all the new branches to form or to do it before then to keep it short any suggestions would be appreciated greatly.
