You said..."I did a little research on the tongue problem and I found that it could be calcium deficiency"...you should ask the vet about what the ratio of calcium (13.8) to phos (5.5) was. I'm not a vet, but I think your test results you posted indicate it's ok....but I'm not sure because I'm not a vet...however, the tongue issues could be from other things...injury, infection, etc.
Lowering the number of bugs won't cause a calcium defeciency as long as you're still dusting the insects properly and feeding/gutloading them properly.
