I know there was a thread here somewhere maybe it was in the advanced technique that had the % of Mg and S in epsom salt and the ppms associated with it.
If I have just the %s can I use the canna stat calc to figure out ppms? seems like it should work but just checking, I havent used epsom in like a year and want to be on point with it, thanks!
