Like Grover, I'm not interested in discussing whether or not PMDD works.
There are lots of testimonials to it's success, but...
In the absence of any information indicating a deficiency in anything that
can be added with PMDD, why would you recommend that Grover use PMDD to
solve his stated problems? How should he go about formulating and gaging
his dose (keeping in mind that iron always reads > 0.1 mg/l with his kit
in his water and the plants aren't showing deficiency symptoms)?
