It looks much more like sodium acetate, and not like mescaline sulfate. I've never seen such crystalization with mescaline sulfate, its crystals are different, there are needles and shards structures.
Never tried methanol or ethanol with mescaline sulfate, but I would definitely expect similar behaviour, as m. sulphate is soluble in water (but not very soluble), but not in IPA or acetone. It's probably about polarity of solvent, methanol is more polar than ethanol, so methanol is closer to water and ethanol is closer to IPA.
