Thanks for the pic Wise Man, very helpful! I'm gonna wait till about 2 weeks into flowering to top them, hopefully they grow a lot by then :grin: !
I went down to my local hydro store this afternoon and had a chat with the owner (very knowledgeable guy!), although I wanted to pick up a Canna Flores A & B set, he put me onto a great sounding, lesser known hydroponic nutrient call Plantastic (http://www.hollandforge.com.au/contents/en-us/d120_plantastic.html
). Sounds really good and wasn't too pricey either. The way he told it; sounded like Canna was good but spent more money on adverting and that's what you pay for! We'll have to see how it goes, keep watching for a review. I fed them this evening at half strength to start out with. Will only feed every 2 or 3 watering to start with, then up the ante as the nutrients run out in the soil.
Happy growing everyone!
