Those plants don't look bad to me, and these are early leaves. I think the affected roots are limiting what she can intake from the water. The fact that the growth still hasn't slowed tells me that they want to live and thrive. If hydrogaurd fixes the roots, i would try that first. I am not sure how long it takes, but the reports have been that it works quickly.
Also, I think those days of us growing 130 day plants are done with this round. You could be almost a quarter of the way done! I wouldn't scrap them. Now if they were the size of your Dinafem with root rot, that would be a different decision for me. I am still just a noob, though. What do I know?
