Plant Guild Kit -- roll my own
I got a Plantguild Kit and make my own, plus I use AP PlantTabs sometimes. I found the original formula was better with the PlantGuild kit. The second time I used Osmocote and added some K2SO4 (just out of the blue I dropped this in) and had problems with swords, maybe not related, though.
