IM CURED!

I added another layer of yellow fluffy fiberglass. This guy was throwing someout around the corner and he let me have it so I added it onto my cloud trap above my mix position. The results were incredible. Since the yellow fluffy was light I wasnt worried so much about the weight and I just stapled it over my original structure with fabric. from 100Hz up it is smooth sailing over here

Could it be that the rockwool I had in my cloud was either too thin (3" + 2" airgap) or perhaps it was not as good as this lower density fiberglass I added? The Rockwool is 70Kg m3 so around this forum that seemed to be a good density.
