Where is that nutrient uptake/pH chart?
I know I've seen it on a couple of threads somewhere in this forum. It's a graph/chart on all the nutrients and how plants uptake them at certain pH levels. I'm not talking about the list of nutrients in the Fertilizer thread. The one I'm thinking of runs left to right in more of a graph. At least that's what I remember. Can anybody please link me to this if it rings a bell. Much appreciated. Thanks.
