Leaf septoria? What to do?

A question from a fellow grower:

See the attached pics.
I have researched this and think it is leaf septoria.
The plants are merely seedlings?

Thanks for posting my question. I worked out that the top feeds were the problem. Too much water/moisture. It’s a DWC setup. The nutrient bath is all they want. After turning off the top feeds and cutting off the infected leaves the plants seem to be recuperating well.

Yes. You definitely do not need to top feed in DWC.
