I used Canna coco and their A&B only. I was seriously over feeding them for two weeks, while budding, with no burns. So if you feed according to their schedule (http://growguide.info/) there should be no problems. No bugs either.
I did play it safe and started with pH:ed water only. After 2 sets of leaves I started the light feed (1/3 of what the chart says) and went to heavy after 30 or so days.
