Plant Deficiency Chart

I stumbled across a great illustration showing various symptoms of nutrient deficiencies in plants. Figured I'd share:

I think I am going to print this out and tape it under my aquarium. Thanks Kris!

I've seen that chart before on plantedtank, apparently everyone there, especially tom barr, hates it

What do they hate about it?

A number of things, like being too generalized and formulaic, and it doesn't include CO2 as a factor, which tom barr is obsessed with. Also, it defeats the purpose of EI dosing since it assumes all nutrients being equal except for a single limiting one. It was a while back so I don't remember exactly what was said. I personally think it's a decent guideline.

Ah, I see. I suppose any simple chart is going to have its limitations, but I do feel this is a helpful starting point for determining what is going on. For instance, I often start a tank off with standard EI dosing, but then tweak it downwards after awhile. If I know what to look for in the plants, that helps me see if I've gone too far.

Why tweak it down?
