Old leaves and newer leaves drooping and spotting

[elderlukebarlow]

Hey guys,

my plants are about 7 weeks old, all in a shared drip ring hydroponic system. On only one of the plants, it started yellowing and drying out, especially the new leaves. I’m using the same exact nutrient solution on other plants, and I don’t think it’a light burn either. What do you guys think?

I think I would be looking at the roots.

I don’t think it’s the roots. They look white and pristine as always. PH is at 5.86 so that’s pretty good too.

Any other ideas guys?
