i need to know if i can cut off the upper branches by the Main stem (BTW it is a six footer with 17 colas/ stalks) , because it looks like the upper buds will mature first, but i dont want the plant to die , and i need the other mid level and lower buds to finish maturing , or do i wait until all the buds are fully mature ( 85% brown / orange) then cut the whole thing down ?
