justsoso i am recovering from a few weeks of very slow seedling growth in Canna coco. I have been researching for a while and have heard a lot of differing advice.
first of all STINKY IS THE BOMB. So obviously read closely what she types, i know i do.
I was told that canna coco should be flushed with calmag if it is fresh out of the bag. It is loaded with K and adding flushing with calmag will supposedly replace some of the K with calmag.
I have just today switched to RO water because my girls + boys were getting water from a new source i was unsure about (220ppmtap).
Also i had better luck when i let the coco dry out a bit so the roots would search for water and grow. That helped some.
I feed botanicare and am at 7.5ml grow and 5ml of calmag/ Gallon with r/o.
They have continued to look like they are not getting enough Nitrogen, and i wonder if the extra K in the canna can lock out Nitrogen? I know someone who probably knows the answer...coughstinkycough...?

Just some nute for thought!:jointsmile:
