My son is 12 1/2 islamically and 12 and 2 months according to Julian calendar. He had some discharge. I dont think he had sexual feelings or thoughts and had ejaculation. Does this mean he is baligh and fasting, prayer and ghusl are waijib on him?

What are the signs and ruling on buloogh because i dont see it in the laws book of Sistani?

by

One of the following three things
Growth of pubic hair
Ejeculation of the seamen
Completing 15 full lunar years.
If none of the above the boy is not balig.
Even though such discharge starts to appear it is better to train him of the precautionary measures such as Ghusl and Salaat if possible.
