Too Much Growth.

...............................................

Man that's a jungle. How did you not account for the stretch? They won't get any taller...but you're going to run into problems with the buds touching each other.

+rep for being a bush master, ill give you 2/1 the light gets eaten.

How bad we talking if the buds start touching from plant to plant?

i dont do touching buds so dont know what was meant by that, but the biggest problems i see is that air and light are gonaa have problems getting around to the middle of the plants never mind the bottoms. i would try and get some light down below if you could or yield will be affected. that really is some crazy cramming!
