I agree I do not top my autos when they are vegging, I might defoliate leaves covering inner canopy bud sites, if I cannot tuck it. Some autos get so dense you have to defoliate sucker branches and leaves or you will get many small flowers, one tip I would tell, I learned from Nate at Humboldt Seed Company when he started breeding autos (I have ran many of his autos, fantastic breeding) when the bud sites are all made, remove all branches and leaves a foot below the canopy, you will increase yield and bud size immensely. In my experience it does not set the plant back but a day or two. It makes the plant focus all energy on the main bud sites left. We do not want to grow leaf we want flowers. This is the idea behind super cropping with photos, forcing the plant to focus on the top best bud sites. Just my two cents, there are many fine growers that use different techniques to achieve the same goal, one is not better than any other in the eyes of an individual grower. We are individuals and unique in our own beliefs. Wow, I’m really stoned sorry to ramble.
