- What I got...
The high carbonate count in your tap water requires a little more PH down, use nitric acid in veg and phosphoric acid in flower. It should be fine.
So I have not been using nitric acid in veg but trying to find some now so i can do this the proper way..... BUT I can't seem to find the Dutchpro ph grow (nitric acid) that you use on amazon.. dutchprousa and hyrobuilder both have it and are fair on the price <15$ but they want 30-50$ for shipping Do you have any other suggestion for nitric acid or sources or should I just bite the bullet and pay the shipping
