So far I am after a cheap fertilizer regimen, MG tomato water soluble fertilzer is what I use. If I use gypsum to get sulfur and calcium, how much should I use? I would like a powdered form that I could mix right with the fertilizer, is that possible? How much?
Please any info would be nice. For the most part, I only worked with expensive 3-part fertilizers that did it all for me, I want to have a more economical base.
When using it in the 5-1-1 and other soil less mix's I know there is Ca/Mg from the lime but no Sulfur, could it hurt to use the gypsum?
Thanks in advance.
Another question. It takes one tbsp of lime per gal.to balance the 5-1-1, how about pure spag. peat?
1tbsp gal for peat too?
If you can answer either one please feel free.
