calcium, potassium, sodium, magnesium oh my

:hi: farmers!

Thanks for a great site. I did some searching but couldn't find the information, I apologize in advance if it was missed.

Overall PPM and PH is what I've always monitored. What about monitoring calcium, potassium, sodium, magnesium on an individual level? Are there general guidelines established for such monitoring? Is this just not necessary?

:nerd

Monitoring individual elements is only efficient for large greenhouses, and only for solutions that are never or rarely changed.

For non multi acre greenhouse operations, and for a plant as valuable as ours, either change it once a crop to once weekly, depending on your style and need, or run to waste. (Which can waste less water than regularly dumping reservoirs)
