Im being diagnosed with hkpp or gitelman. if i have brags apple cider vinegar with salad ... could this worsten potassium levels?

I don't think so: This is a very specific question and is likely best answered by your physician and clinical dietitian. In general, dietary adjustments to include foods high in salt, potassium and magnesium are needed. The nutritional label suggests that Bragg's apple cider vinegar is high in potassium, so I would think a reasonable serving of this would be fine. Again, your nutritionist can help. Good wishes:)
