I was reading in the grow bible about pruning but after reading it I was left with more questions.When do I prune,in the vegetative stage or in the flowering stage? What do I cut off,the lower fan leaves or just the new growth?
I’m sorry I have so many questions,I never grew anything before starting my cannabis.
Sometimes I feel that when you 1st start growing; You should enjoy your early grows, and learn how to grow your plant as simply as possible.
Learn your method, learn how to adjust and apply properly PH’d nutrients.
As the plant matures; You can see how the different stages take place. 
If you fel you have to prune; Take off small growth from around the main stem after main and secondary stems have matured. Do not remove fan leaves. Light pruning is best, and nest done in intervals. Peace
