Adding Epsom salt, frequency?

I have a cal/mag defiency and watered with 1tbs of Epsom salt (per gallon) 1 1/2 week ago, and am still noticeing the defiency somewhat. Will it be cool to feed another tablespoon(15ml)??

Yes, but you might reduce to 1 tsp/gal if you're only noticing it somewhat.

Well somewhat to moderate. Let say I use the full 1tbs, is their any kind of possible ill effects that could happen?

There is an optimum ratio between mg and ca. I don't know if 3 times the mg necessary would upset the ratio enough to interfere with ca uptake.

To me it gets back to why give as much mg as when the def was very noticeable now that it's somewhat noticeable? The plant seems to be saying it doesn't need as much. Giving more than necessary seems like it would tempt an unnecessary problem.
