Question Phrag leaf discoloration

A few of my phrags went over long before repotting about a year ago and some began showing some leaf discoloration. (Roots were ok, but not great.) After repotting new leaves have continued to develop the problem. I virus tested the worst affected plants and they were negative (Agdia test). As shown in the photos, the discoloration shows on both back and front of leaves. Could this be a fungal issue?

Additional information: Plants are watered with RO water and grown in a greenhouse.

I would say bacterial, not sure why it would be that bad on a Phrag.

Hopefully others chime in with ideas on treating such an extensive problem.

Do you have good air movement and temps over 50F?
