I should have mentioned I don't use Canna products in veg except the Rhizo. I have no idea how they work in veg and don't want to know. Nothing will beat the cheap Maxigro powder and some additives like MBFerts Vitamin & Hormone Booster. Don't use the V&H booster in bloom, unless you want some crazy ass stretch. As far as Rhizotonic it's GREAT, but not in your feed. It's the best foliar on the market. Once every 3 days at 7.5ml/gal. It's not expensive at all if used this way and works better than dumped in the feed.
