I've been running raw salts for a couple of years now, and am beginning to have enough knowledge to know some things I don't Know.
1. Water Analysis. I figure my W.A. into my formulation, but are all those elements in a form which is available to the plants?
2. is CaCO3 plant-available? Does it dissolve into such a form in solution? I see GH uses it in a couple of cal-mag products.
3. does acidifying the solution free up unavailable ions? Seems like I read that somewhere.
4. if the solution pH goes too high, and precipitation occurs, can it be reversed by dropping the pH?
5. finally, the $20,000 question: What are the differences in formulation between pure hydro, and soil (or similar cec-containing media)? I'm growing in bio-buckets (RDWC) which has pretty much zero cec. It seems that the wisdom a couple of years ago was a K:Ca:Mg of 3:2:1. Now I'm seeing higher Ca, and lower K. Could be other issues, but it seems I did better the old way. Is that maybe the difference between hydro and coco?
Many thanks for any thoughts you may have!
