Well spotted. I’d want to avoid Chlorides in these mesonutrients at least (see @NarcisP’ reply here) although I’ve just checked that they used CaCl2 according to their 2023 paper[1] I have a feeling that avoiding chlorides altogether may increase yield (unless of course the bugs actually need chloride in which case we’re stuck with a balance of meeting that need and bleaching them.
