I’m using Coco Coir for my medium. Plan to start seedlings in a small pot and move to a fabric pot in a week or two. Decided to use Canna A&B for nutes.
Question is, should I use Canna Start for first couple weeks till seedlings establish or go with A&B from start?
In coco, I think you can hold off feeding for about a week from germination, til the cotyledons (the first little round leaves of the plant) turn yellow. Since coco doesn’t have any nutes, a week or so is probably how long the cotyledons can feed your babies before you need to step in.
Best to start at about 1/4 of the recommended dose, then slowly increase it as your plant gets bigger & hungrier.
