I just wondered what are the types of plant deficiencies, and what they look like?

Can anyone tell me what would happen to the leaves/what would happen in these situations

potassium deficiency
iron deficiency
co2 deficiency
nitrate deficiency
phosphate deficiency

Here is a link to nutrient deficiency symptoms.
Nutrient Deficiency in a Planted Tank
CO2 is not listed.
Perhaps slow growth could be listed as a CO2 deficiency.
Another could be the presence of algae in a heavily planted tank.

lol...

Give the plants everything they need and you will not need to study or worry about which deficiency is which.

You have asked the wrong question.

geezer

That's just stating the obvious and not helping out at all, like the majority of your posts.

Thanks for your help wiste

geezer,

You have it all listed (See quote) N,P,K,TE, C02, Light, add water, dose 3x a week,
You have 260watts of light on a 55 right? obviously. that is to much light which I presume is why you are having problems and looking for deficiency list.
I will jump out on a limb here and say you are deficient with the C02 and that amount of light, turn some of your light down to around 192/200 watts will be plenty for no more than 10hrs daily, 8hrs for a few weeks would help alot. you can even run less than that a couple times a week would not hurt a thing, simulate nature, to a degree.
No need to blast 300 watts every day all day.

I really do hope you get it under control, and this is exactly how to do it.
Good luck.

Turn down the light some.
Dose:
50%H20 change-weekly
+/-1/2Tsp KN03 3x a week
+/-1/8Tsp KH2P04 3x a week
+/-1/8Tsp K2S04 3x a week
+/-10ml Trace 3x a week
+/-2-4ml Fe/Iron 3x a week

_Dosing Regime's_

There is a correlation between light and C02.
More light=much more nutrient's, especially C02, when you start driving a system that hard, error is much easier to achieve.

thanks craig for your help, i've recently upgraded the tank to 95 gallons so now it's easier to keep under control than the 55 gallon

a few of the leaves have tiny black/brown dots which aren't that noticeable.

i was dry dosing with csm+b but today I've gone to TMG instead, and will dose the extra iron/phosphate/nitrate during the week.

hopefully i can see a change!

thanks for your help again

potassium deficiency - brown pinholes appear in older leaves; rotting of leaves, stunted growth

iron deficiency - new leaves grow pale and yellowing. In case of red plants
their young leves are pink.

co2 deficiency - stunted growth, weak pearling, wilting of leaves
nitrate deficiency - older leaves beacome yellow, in severe deficiency they rot and fall off. When deficiency is not severe some plants (such as Rotala rotundiflia) lean sideways and they look as if theye were "running away" from the light. Some plants get rich colors on their tips.

phosphorus deficiency - stems get pinkish colors, stunted growth, poor pearling. Somne leaves (for example on Heterantera Zosterifolia) become black on the tips.
