Nutrient Interactions

Before I show you a chart that looks like a spiderweb of mindfuck called Mulders chart of nutrient interaction, Ill try to explain how to read it a little so people can use this as a tool in the box for their grows.

When you have an excess of one nutrient, this can make other nutrients react in positive (synergistic) or negative (antagonist) ways. Synergistic interactions will increase availability while antagonistic will decrease.

For example, lets start with Potassium. An excess of in K helps availability in Manganese and Iron but decreases the availability Nitrogen, Phosphorous, Magnesium and Boron while doing nothing to others.

This can then be applied to the whole.

This chart just blew my mind.. So what this is saying is to mix a balanced food. Rather then try and give what the plant looks like it needs...
So what if I am using coco (my first time trying to lock a coco grow down) and the K is already naturally high? How can I counter the nutrient antagonism, and get a more balanced mix? I currently use Sensi coco grow and will be swapping to bloom in a couple weeks. I want to make sure this harvest goes without a hitch

I assume most nutrient companies creating a mix will take this understanding into account (although this is the cannabis field,where unicorn poop is big money so who knows). This would most benefit a soil maker who is creating a blend and can change inputs at different ratios.

First let me say that I wouldn't use this to chase deficiencies but rather just use it as a tool to understanding and diagnosing.
In your case, if your really did have higher K amount, you may have to increase the amount of N you are feeding but I wouldn't recommend that unless you know you have an excess. Increasing N will increase Mag and Moly while decreasing K.
