Hey Guys/Gals , this is my first grow. Basically just a hobby for shits and giggles. I have attached 3 pics..
Question 1 .... What do the light spots on the lower leafs mean?
Question 2 .... Is it possible to determine the sex yet? Or do i need to wait till i begin flowering?

Any suggestions are welcome..
Cheers
