well, i wouldnt say weak, have revegged many times, they always do this.
but i do find that indoors, you dont want more than 4 tops per plant.
dont know about outdoors, but indoors you get weak buds(compared to the 4 tops method), lots of them, but much of them is shaded from the light by the other tops, so dont really mature that much or get big. get a shitload of them though.
its the difference between 4 thick all the way down buds (if done correctly) compared to 20-30 wafer thin sticks with a lollipop on the end, (if that)
maybe outdoors its fine, the earth rotating around the sun and all that.
but indoors, i trim revegged plants and heavily.
you might find othervise, but thats so for me.
but to be fair, you´d get more out of this 20-30 top plant than a plant grown regularily (one top with bushy bottom popcorn thats 1-3 feet further from the light than the top )
