i have three plants growing and they need to be pruned. 4th week veg. each plant is being grown differently. 1 is growing wild, im letting it do its thing. my second im using for clones and going to try the topping technique. on my third plant im doing the scrog method. being this is my first grow i wanted to try different things to see which works best for me. but i need to prune some fan leaves. they are getting so big and blocking so much light but i dont want to take too much away cause it is still in a veg growth stage, and for at least another week. suggestions on how i can properly do this? also dont want to cause too much stress on the plant.
