Nutrients missing?

Does the look of these plants suggest that there are some nutrients missing.
Does the way that the top leaves twirl down suggest that I might be missing something like Iron or K?

I have the same symptom on some of my plants: leaves bending down like that. Have not identified exact cause, but right now Mg is my prime suspect.

OK,
would the solution for that be epsom salts? That is Magnesium sulfate, right? Im no chemist
Im dosing 25ml of Tropica master grow a week, but I only have a 5L jug of TMG and the ingredients dont follow, so I dont know how much Mg is in there.

Epsome salts it is.

So, how much epsom salts would one put in a 210ltr (55g) tank a week?

I am starting to use epsom salt, can't say it is the cause yet. The only reason I think it is the suspect is I made sure I have enough NPK/iron/trace/Ca, Mg is the only thing I am not sure. I am getting a good Ca and GH test kit to know exactly how much Mg I have in the tap water. I am starting to add 1/2 teaspoon in a 100gallon right now after water change, might try a little more.

Sven, please do NOT ask me how I got here - I have been reading and studying all day! But I finally arrived at 1/2 teaspoon Epsom Salts with water change and 1/8 every other day w/ one day off for my 20 gallon tank. http://www.barrreport.com/forums/showthread.php?t=1 and
http://rexgrigg.com/ferts.htm were the 2 biggest influences I found! Now - this was based on the information I gathered and my water parameters...

Good luck!

OK, so I have been adding epsom salts for almost 2 weeks now and the plants are actually getting a bit worse, but it mainly seems to be the hygrophila that is showing signs of this deficiency.
I put in a order with Greg watson for some Calcium Chloride, Im thinking that will help remedie this problem, is that right?

Nobody has suggested Potassium. Infact I did not even see anyone mention it in their water parameter testing.

Well, My Lamotte GH and Ca kits arrived and it says I do have Mg in tap water. I am going to monitor tank consumption. Maybe there is something else that is missing, the search continues.

Potassium is still a possibility, maybe we are underdosing. I have increased K dosing as well.

You list DIY CO2, those smaller tips look like classic poor CO2 levels.
Mg deficency does NOT express itself in that manner, you folks are confusings some Ca issues with Mg.

I'd centainly add a little Mg in the water there, it's likely very pure with little GH or KH. But 1/4 teaspoon of MgSO4 * 7 H2O 2x a week is plenty for a 55 gal tank no matter what the light.
CaCl2 can be added for the Ca++.

SeaChem Equilbrium, if you can get it, would add K, Mg, Ca, SO4, Fe and Mn.
That would cover most of the bases and leave you with CO2, KNO3, KH2PO4 and trace dosing. If the KH is 2-3 or higher, then you are fine, if the GH is 5 or higher, the Ca is good.

Still, I think the tank has poor CO2 issues and that is evident from the algae on the background and on the plants.

Fixing the nutrients is rather simple, fixing the CO2 may be tougher, you need at least 2 x 2 liter DIY bottles going and a good reactor/method to dissolve the CO2 and mix it in the tank well.

That (improving your CO2) will help you no matter what else you do.

The algae has actually been going rapidly away.
I have 2 DIY yeast bottles producing a bubble every 1,5 - 2 sek. The reactor is a powerhead on a gravel cleaner, seems to be dissolving the CO2 100%.
Last time I checked my GH was 40 mg/l And KH wag 1,12 German degrees.
Should I be using equilibrium as well as epsom salt and Calcium Chloride, Im also expecting the PMDD mix from GW.

Well, I increased my K dosing and the symptom went away on my hygro.
