Deficiency or Disease?

Hey all, over the past week the leaves of my plant have started turning yellow with brown spots. I have been ph’ing the water and only feeding light nutes (1/4 strength) other 3 plants are going fine and it seems that this “sick” plant is still fattening up the buds, so I’m not sure what’s going on.

I thought maybe it was a K deficiency so I gave a double strength feeding yesterday, but don’t see a difference (might even be a little worse). It started on the lower leaves and spread up. I want to think it’s not disease because my other plants are in the same tent and doing fine, but now I’m freaking out.

Any help would be awesome!!
