DIY N03 solution using Sodium Nitrate

[Ziggy17]

I know I’ve seen a link here somewhere but I can’t find it. I thought James planted tank had it but it only has potassium nitrate as an ingredient. If you can post the link with the direction on how much to mix and what it doses, I’d greatly appreciate it.
