Forgive me if memory is a little faint, as this was almost 15 years ago. It was root fursarium. Plant looked somewhat ok in veg, a little pale, small root mass, stunted growth. During flower, plant would just start to yellow, drop leaves, and slowly die. If you were able to finish, pathetic small buds, no flavor or smell. This was on a strain that you could pull at 7 weeks, large yielder, beautiful flowers. If it was something that went 10 weeks, you would never make it, it would be dead.
Yes I would cut my losses and start over.
