how do you tell nutrient deficiencies in algae ?
i'm familiar with freshwater, and many nutrient deficiences include paying attention to the veins in the leaves of plants, ... but algae as a non-vascular plant doesn't have veins.
what resources are there to help identify nutrient deficiences in algae
i don't think there's enough to tell in micro-algae, but macro-algae i'm hoping would provide enough to help identify more.
am searching for answers, but also very open to any input available, ... as this is a search i've never tried before i don't know where to begin, i can only imagine everything is going to point me to freshwater vascular plants :(
really am looking for help identifying nutrient deficiencies in non-vascular plants & algae
