Accurate and precise are the same thing.
Blumats are for watering soil I thought. They would be bad for coco. Localised salt accumulation. No flush. But worse than that, coco is great because of it's air exchange potential, which constant moisture levels put a stop to. And don't forget the flood. There will be a flood. So stand your plants where a tank full of water can be caught.
pH can be read various ways. We don't need that thread detour. Just read it.
Lucas formula is mixing two bottles. Isn't nearly everything? Simple would be just one bottle. Using Nitric acid for veg and phosphoric acid in flower. Then the only second bottle to think about is PK.
Keep in mind that a organic feed, is usually a feed sourced by organic means. Immediately available plant food. Not a tonic that feeds something, that eats something, that shits out plant food. I have stuck plenty in coco, which is so similar to soil that you can almost ignore the differences. Lots of soil even has coco in it. And it's perfectly capable of housing a microherd. CoCo food doesn't work well in soil though. Only soil feed in coco. Which is good news when looking after plants in both substrates, or if you have some soil feed to use up, when your coco specific one runs out (when your blumat's empty the last barrel, perhaps)
