My macros are old, but KNO3, etc are basic chemicals. They shouldn’t really break down. However, my KH2PO4 is clumping, and I’m having trouble with algae. So, I thought I’d buy new N and P because, what would it hurt?
Today I am completely out of my current fertilizer formula and needed to make the new mix. I gathered my old containers, dumped the first one out, and realized it was the K2SO4. I didn’t buy any of that.
In the midst of an algae war, I have no potassium
Luckily, it was the first one I poured out, I only needed 2.4gm, and it was piled on top of the trash. I was able to scoop off just enough.
Placing an order for a new bag now.
