top at 3 weeks

3 weeks there still pretty young and still use all there leaves for photosynthesis, imo its just to early to start cutting leaves off..
 
You can really top whenever you want to. I have heard its good to top with your plants are around 14" and then let the lower bud sites grow up to the top before you flower. I am going to try this method on my grow. KP has some crazy topping for mother's where the plant is topped way before 3 weeks veg. I think starting at the 2nd node KP? Maybe... :joint:
 
After about 4 or 5 nodes appear and/or after the nodes start alternating. Size and health, more than age, should tell you when to top.
