Brown spots on yellowing leaves

Soil
Ph is 6.2
Temp 81
Hum-60ish
Ppm about 800

last week I fed them and forgot to ph my water. I corrected the ph the next feeding but my plant are looking under the weather still.
Is it just taking time to bounce back or am I dealing with a different deficiency or problem?

I attached photos of the brown spots and even The healthy ones have a little yellowing.
What should I do ?

thank you for the help

IMO - remove all the leaves with brown on them.

Agreed - some of the leaves have dead tissue, some are just yellowed. Remove the leaves that have dead tissue.
