Just began mixing my own DIY ferts. The macro mix I think I've got sorted. And the CSM+B.

But, there's also a bag labeled 13% chelated iron, with the assorted bags of fert ingredients I got. There are no instructions on how to use it.

There is no information on what else it contains, should I assume it's EDTA?

I was using Seachem's Iron, I'd like to use this instead. I will when I know how to mix it and how much to use once it's mixed.

You can *probably assume that it's edta since that is a common % edta comes in. It's listed on rotalabutterfly

Either way, 13% is 13% so you'll get the same ppm regardless

I need help with the calculator. If I'm honest, I'm a math moron. Always have struggled with numbers. Ideally, it would be lovely just to be told how much of my iron mix to add to a 500 ml bottle of RO water.
