| The thing that caught my attention was "Water/Paint ratio".
Acrylics should require very little, if any, watering down to be able to spray it and the effects that you are experiencing all sound to me like you have too much water in with your paint.
I would try with neat paint first on a test sample and see how it performs and if you still feel the need to thin it I would use the correct proprietary thinners and not water for this.
Water evaporates at a completely different rate to the paint so can mess up the curing process on the model. The correct thinners is designed to evaporate at the same rate as the paint so is necessary to use when spraying. You can get away with water as a cleaning medium but, to be honest, it may be cheap but it is not as good as a correct solvent anyway so spend the money and use the correct thinners.
