These plants were started in peat moss jiffy pods and transplanted to potted coco with 5% nutes in the 6.5 pH range. They grew slow and had floppy leaves, which I attributed to overwatering. I have since then tried everything from 50% to 100% of the Canna-recommended 1.0 EC, but the are looking pretty rough.
Some sources say that coco is impossibly to overwater with. Other people say to water once or twice a week. Others say everything in between. pH levels are the same story. Source A says 6 to 7, source B says 5 to 6. ???
Are these plant being overwatered or over-nuted? They have so many signs of different deficiencies and toxicities that I'm at this point: Any help would be greatly appreciated!
