Alittle Cal Mag and no deficiencies in the first place. Preventative maintainence.
In large amounts, yes, I agree, it can inhibit production, and can increase, if not used correctly, problems. In large scale applications, and provided the preservation of the micro-life underneath the top soil as well as the plants vascular system, Epsom salts can help a great number of plants and their needs. Run on sentence, I apologize though. I also agree, CalMag and other products within the limestone realm may offer better results.
Magnesium helps with the Chlorophyll production and maintenance, as well as cellular health. Increased flower production may be influenced, but it not a typical supplemental tool. High flowering or fruiting plants like Rosa, Cannabis, Vaccinium, Capsicum, Rubus, etc. etc. will all benefit from mag supplements, within reason
Sulfur, without writing a book, is responsible for overall growth of the plant, reducing environmental stress, and helping increase pest and disease resistance.
I apply once every 2 to 4 weeks, when needed, but I have a great deal of magnesium and sulfur ingredients within my living soils and teas.
