I'm not fully trained in the arts of mental health... But I did minor in Counseling as an undergrad. It seems to me that my professors largest complaints were not related to being drug down by constant complaints RE demons coming out of the walls (though he did have a few patients I'm sure), instead he was drug down by the monotony of having 30 clients (A light load no doubt) all with the same story, and minorly different details...
He said once a year he has to go off and have a good cry... But that over all, the hardest thing to overcome is the monotony - continuing to act interested when for the 20th time this week, a couple comes in with the same communication problem RE money.
If playing fast and loose with your plants calms your nerves, then more power to you. The rest of us are not in it to grow the hottest pepper, or the fastest pepper either... most of us do it for the love of gardening, and more particularly the love of the plant and pod.
This makes /most/ of us want to do whats best for said plant/pod.
Which means most of us have very similar products in our garages...
I think its not until people truly understand how similar to everyone else the desire to be different makes them, that they can really be free to actually be different... Where it counts. You wouldn't try giving your child vitamin C, when they needed chemo, radiation, and a tumor-ectomy... Don't do the same to your plants... It may not be cal/mag deficiency... But know going in, if it is, and you dink around with cures that aren't effective, that your plant will probably die.
That said, epsom salts are a good source of magnesium and sulfur, and egg shells are a good source of calcium... The water off tuna in water, is well received by my plants (high in nitrogen).
Lastly, if you are trying to do something different, asking for advice only gives you more roads that you can't take...
Just kidding 
Good on ya for taking on a tough job!
