I agree with Tex, there is not much you cant do with them besides clone them.  That is natures way to kill them off if you think about it. lol.

Topping them seems to keep them in veg for about 5 weeks so they get better. My first grow in the RDWC were Autos and I decided to keep feeding  the grow nutes to them and that was a huge  mistake. The damn things never stop growing as is.
