I have treated all of my plants - including adductum - with the stuff since the company asked me to carry it back in 2014, and I have never seen a negative reaction.
To this day, my biggest customers are breeders who buy it specifically for ex-flask seedlings.
I have a dozen or so other compots alongside my adductum, all multifloral species and hybrids, which seem perfectly happy with garden solution but every time I gave it to adductum a few would rot out within 24 hours. I have no idea why, they would be growing perfectly well all month then just fall apart into a pile of leaves after application.
