Miracle Gro in my compost

[electricthot12]

I always reuse my store bought potting soil after composting it. I add composted cow manure, wood ashes, and other stuff and let it compost. I feed strictly organic nutes. Until I ran out for a period recently. I had to finish a grow with miracle gro flowering formula which I had on hand. So, is all that soil throwaway now? Or can the salts be composted out?

It’s still useable, if you’re worried about chelated salts, give the soil a good flush (3x the volume of the container), let it dry and do your amending. It’ll be fine.

Thanks. I've got about 6 cu ft of it, and have a lot invested in it. And it would hurt if I had to throw it away.

I re-use FFOF all th time, Iflush, then re-amend, nver has any issues. Good potting soil is expensive!!
