Hydrocorn PPM Problem & Canna VS Biobizz Nitrogen Question

I am using deep water culture and even though i've done about 5 water changes I still notice my PPM builds up over time and I notice a lot of residue in the bottom of the buckets. My roots are going slightly brown but have been this way for a fairly long time and seems to be improving, i'm guessing it's picking up the junk floating around of the hydrocorn?

And can anybody tell me what chemical compound of nitrogen is found in biobizz and canna? For my particular plant i've read nitrogen as NH4(+1) + NO3(-) reduces potassium intake dramatically and this hinders growth compared to nigron as NO3. :confused: I've also heard a lot of plants suffer from nitrogen deffiency with biobizz.
