Thays the first one I've seen that looks exactly like my problem. So it's a calc problem. I thought calc always shows as the dots. I had no warning of dots. Just immediate necrosis patches. I'll get some cal. Thanks a lot. I see mag def on there too whoch looked like what I had. I'll start using an upped calmag amount. Thanks mucho man.
