Why do my leaves look like this?

Usually 6.5 for pH, I'll have to be honest, I don't check the PPM nearly as much as I should. So I will have to double check. I appreciate all the responses!
I believe what we're both asking is to check the runoff. Feed 6.5 water in, collector run off in a clean pan and check both PPM and pH of the runoff
