N and Mg tests are very inexpensive but 40 samples testing both at about $1,000 does sound about right.EasyBakeIndica said:It's about $1,000 to have a set of 40 samples tested. You have to find a research facility which will work with Cannabis (IE: Universities in California, Canada, and England). Some won't ask questions, especially if nothing is labeled as 'Cannabis' or 'Marijuana'.
I think there's so many myths, urban legends, misconceptions that could be quickly cleared up with some basic testing...someday.
The focus here seems to be on N and flushing but something being missed, I think, that will probably affect smoke quality more might be the trace mineral/element concentration? From what I understand excess N is pretty easy to get rid of, both in the soil and plant, but excess trace minerals are harder to translocate/flush/etc. Just going off info from a knowledgeable grower friend on this one.
I don't think a water flush will be adequate. You'd have to actually micronize/digest/dissolve the plant material as I'm sure the N and Mg are locked up in the tissue/cellular structure itself. Just trying to leach it out wont work.Couldn't I just do a water cure with both and measure the water with a simple soil testing kit that measures N and Mg.
