You only need one application of the Epsom Salts, don't keep applying it.
Soil meter? If it's one of those things where you stick 2 prongs in the soil, throw it away! They are worse than useless because they give such inaccurate readings. Your pH may be fine and the meter, off.
If nothing else, snag one of those $20 pH pens off ebay (be sure and get solution), and measure the run off pH. That is what counts. Milwaukee 600 is decent and $20.
