@OutForReal provided sound advice. I guess you’ll just slug it out this grow.
Though I don’t grow hydro, I am a swimming pool professional and I understand water chemistry, so I offer this. We can manage water with chemicals from a numbers standpoint, but sometimes end up with a high level of TDS, total dissolved solids, and that makes balancing quirkier. You knew what went wrong, and how to avoid it in future. Enjoy this harvest as best you can and keep at it!!
