You've been getting good advice here fishboss.
Many discus-keepers (including myself) have learned the hard way not to be too hasty with medicating, which could be fatal to them just as easily.
Give them a few more days, treating them as best you can along the lines suggested, observe them/their behavior - see if there are any improvements. Report back on their condition in a few days, and if there has been deterioration in their condition, medication would likely be in order at that time - but it's important to try & pinpoint the actual problem, so that the correct meds for the condition are used. (As best as can be determined.)
