Plant Deficiency Picture Diagram
 
I took the time just now to go through and draw out most of the common plant deficiencies in pictoral form. This diagram is by no means an exhaustive reference for all deficiencies and certain plants vary in their symptoms, but in general most deficiencies will look something like the diagram below.

There is a red dotted line that shows deficiencies that show up in new growth and deficiencies that show up in older growth, this is an important line and attention should be paid to it!!

Hope this helps people identify what they have a bit better.

***Edit***
This was updated as of 2016 and is correct to the best of my knowledge. Iron deficiency is seen in the new leaves only.

***Edit***
THE PHOTO BELOW IS AN OLD VERSION (Notice the red line was shifted downwards, meaning iron deficiency occurs only in the new leaves - NOT the entire plant on most aquatic species).

Nice. Can a moderator make this a sticky ?

What about leaves turning transparent? Would that fit under magnesium deficiency?

Fantastic diagram by the way! I'll link to it on my blog.

Magnesium deficiency is characterized by very dark green leaf veins and some kind of discoloration in the tissue between veins. The exact color depends on the plant in question, so clear leaf tissue is possible.

Clear leaves sounds like a lack of light to me, but it depends where the problem shows up on the plant and could be something different entirely.

Nice graphic, Zapins! For phosphate deficiency, you can often tell the difference between that and nitrate deficiency, if green spot algae is also on the older leaves/glass. That would likely indicate lack of P. Fantastic job!

Thanks very much Zapins for taking the time to draw this very educational diagram. To the best of my knowledge it summarizes quite well what we know about deficiency symptoms in aquatics so far with regards to macro elements.

While the graphic explains issues when macros are in short supply let me add to this when traces are deficient:
New growth in most species will appear twisted and reduced in size. This is in accordance with knowledgeable people such as Amano and the guys from Seachem.

This finding gets overlooked quite often as aquarists seem to concentrate on macros these days primarily.


Thanks again, Detlef

Hi Detlef..

Well, I can't exactly agree.. perhaps in SEVERE deficiency..

Trace deficiency will show in new growth. This new growth will be lighter in color. It's quite easy to see.

What you describe is much more likely to come from Calcium, which is also shown in the image.

And I forgot to underline...

you CAN see what detlef describes even though it is micronutrients that are missing.. BUT it is only in extreme cases.. meaning.. you won't experience it as a 'normal' deficiency due to dosing too little.. only if you outright don't dose at all..

Re: Plant Deficiency Picture Diagram
 
Micro deficiencies are rarely encountered unless it is an iron deficiency, that is why I didn't include them in the diagram. But you are both right. Some micros cause the new growth the be pale (iron), others cause the new growth to be twisted (boron).

Question: for a potassium deficiency, using PPS dosing, which would you increase?
Potassium Nitrate KNO3
Potassium Sulfate K2SO4
Mono-Potassium Phosphate KH2PO4
