Why not suck it and see with the soil amendments? You are obviously competent enough to diagnose and rectify any problems. Perhaps you can tell us what the remedial action might be on discovering that a seedling has been planted out into soil which is too nutrient rich? I'm a bit stumped for solutions which don't involve either digging it up or a new plant. If there is not enough you can always mulch it later I suppose, maybe there are other strategies. I suspect that if I were to leave anything out it would be the inorganic fertiliser pellets, as I would imagine that it could be replaced by liquid feeds (which would be a lot more labour intensive). I'm sure others also have a multitude of other suggestions, and at the end of the day there are no doubt many different ways of achieving a similar result.
Perhaps a good option would be to separate the bed into e.g. three sections, and try a different level of amendment in each one (low, moderate, high). That way you will get to find out what works best for you in your local soil and climate.
Please bear in mind that I grow in pots (I find this can be convenient for discretion) and tend to favour JI#1 throughout, with the majority of the nutrition added by way of liquid feeds. It's a much more labour intensive approach.
