Should be a sticky if accurate! The diagram was great, but it's always nice to see an actual color "picture" too, especially for slow learners like me!

Looks good!

I think it would be better if there was a line across the picture that divides old and new growth simply for ease of finding old growth and new growth problems.

Also, the calcium twisted tip leaf looks like a normal leaf? I'm not sure if there is a twisted leaf in front of a normal leaf since the picture gets a bit grainy when I zoom in.

Anyway good job!

thanks guys for the comments.

zapins,
from a graphic design perspective, i chose to not use the line to keep the illustration as simple as possible. I had the line before and removed it as it was drawing too much attention in the diagram. The visual space itself would be the distinguishing factor as the supporting text somewhat creates these 2 sections.

With the twisted leaf you are right, I was looking to mimic one but couldn't get the right effect. I'll continue to search for one and edit it in the coming days.

I think with or without a line (to define old growth versus new), this really needs to be a sticky. Can't urge that enough. Having a visual diagram like this, with explanations, is excellent.

Could a Moderator please indicate what is preventing this from becoming a sticky, so it can be fixed? The original posts have been great, but a diagram that is more dimensional with color like this is so much better, especially for noobs to the hobby!

I agree that this is one worth being 'stuck'. I am going to print it on my color printer and hang it up by my tanks for quick reference. It would be especially useful for those just getting into planted tanks.

I am having problems with some sort of deficiency and remembered this diagram:) It really helped me out when I first saw it.

Both of these lists/diagrams are missing the most common deficiency I've ever had to deal with; CO2.

Most of it looks like calcium issues, and for the most part those in denial about their CO2 levels (we've all been there) tend to go on and on about their, "calcium deficiency"

I think it'd be worth further defining and adding to the list.

It wouldn't surprise me to see it as N. CO2 can look like K+ as well; structural failure causes holes.

Right now I'm showing CO2 deficiency in some staurogyne from changing my flow dynamics. I'd be screaming N, K and Fe deficiency if I didn't know well enough to look at the staurogyne that's not in dense patches. This is in fresh aquasoil with me dosing more than standard EI under mid to low light levels, using tons of flow, a wave timer and a SCWD, so obviously it's not nutrients or nutrient distribution.

This is why I think there needs to be a discussion on the nature of the deficiency, why it manifests as it does, how to spot it, etc. before it just gets dropped on to a chart as a little side note.

I attached mine to the outtake of my XP4 using a 5/8 to 3/4 barbed adaptor. I hung it with some plastic coated wire off the back of the tank, and used a couple of 3/4 inch outtakes. Right now the outtakes are fan-shaped with a ball joint, but I'd like to flip to eductors and modular hosing.

Using a SCWD and Ocean Pulse Duo has made CO2 distribution WAY easier. The 10 second switching allows two viaaqua 480's to run as needle wheels without the CO2 backing up. I've split the duo's outlets to allow for a couple koralia nanos as well.

Awesome job so far hariom and a great tool side by side with Zapins's diagram, too.

I recently was led to believe that CO2 deficiency can also look like N deficiency - in some plants.

I think the way to properly label CO2 on the chart is, just on the right of the current list, block the whole plant and within say: "CO2". I'm serious -- it's by far the biggest macro and, you're right, it can show any of these symptoms.

CO2 deficiency symptoms that mimic other nutrient deficiencies is an interesting concept. El natural aquariums don’t have CO2 injection, and the plants grow fine. Other factors at work?

CO2 is essential to so many compounds that a lack of it causes multiple issues throughout the plant. Look at chlorophyll; by atomic weight it's mostly carbon, by atomic ratio it's still around 2/5ths carbon with a lot of the rest being hydrogen (not exactly hard to come by). Even more of the plants rigid structure depends on carbon, so that fails with a CO2 deficiency too. Gradually developing (days or more) leaf transparency with structural failure always points at a lack of CO2 to me.

NPT's get CO2 issues too, some more than others. Every style of planted tank that I have ever seen has the potential. there's a bit more of a tendency towards K+ deficiency in these tanksbecause it's hard to get without dosing, and the substrate/fish food provides plenty of N and P. Within NPT's, the most popular style is of course El natural. With this method CO2 is gotten around because the system works on not disturbing your tank, leaving lots of organics to break down to produce CO2, and keeping light low. There are mid-day breaks worked in that help quite a bit as well. Even so, BBA happens in these tanks which indicates CO2 issues. It's more often a matter of experience than being of any major method, because the principles are all the same, and the methods are all well tested.

Showing CO2 deficiencies as an entire leaf thing is a very good idea.

That is a very good question.

Plants can grow "fine" and yet a few leaves on some plants may show a nutrient deficiency. For example, some of the leaves of a single species can show a deficiency, and yet every other plant (all different species) in the tank can look perfect. Also, it is not uncommon for folks that grow sword plants (Echindorous) to trim the outer leaves when they start to look bad. Is the plant growing "fine?" Probably yes. Could it look better, also yes. Can it be grown so that the outer leaves hardly ever need to be trimmed - again yes.

In general, "El Natural" aquariums cannot support the same plant diversity as a tank with CO2 injection and with regular additions of other nutrients. Same is true in terrestrial gardening. So, it all depends on what you mean by "fine." ;)
