Hello Greenies,
As some of you know, I moved to remote northern California and started a analytical lab. Among all our services we perform soil testing for growers through hydro stores in northern Humboldt.
This gives me a distinct view into the practices of this areas intense gardening and the resultant residues in heavily used soils.
In more than 95% of recycled grow media we are finding toxic levels of Calcium that are correlating to only minute magnesium levels. This situation is causes a myriad of issue in all growers with the soil conditions. It starts with what appears like nitrogen deficiency, then lack of vigor, and followed by deceased yields. I am talking half a p from a cut that used to pull 1.5.
I am advising these growers amend with Epsom and suspend all CalMag use. People here just have too much access to hydro stores... You should see all the bottles they have next to the Rez!
Anybody seen this before?
