I wondering if anyone has used the Canna products. I tried it on the first time out, and wasnt sure I got the results I should have. I was talked into buying the line of products: fertilizers a & b for veg and flower stages, rhizotonic, cannazym, and boost. I found that after watering using the chart, my leaves would often get brown spots like burns. When all was said and done, I was not very impressed with any of it except the boost. (rhizo is good for taking cuttings and rooting fast in water, for those that have a hard time getting cuttings to root) Can anyone recommend something else or advise on the Canna line?
