Hi this is my first grow im doing 2 gorilla glue, 1northern lights and 1 og kush. I just wanted to know if it would be a good idea to defoliate my autos at all as 2 are 4weeks old and other 2 are 3weeks and are quite short and bushy (PICS BELOW) plus does it look like i will have enough room in this tent for the 4 plants or do they look like they will be crammed together as they grow bigger.Any advice would be greatly appreciated
