Hello Everyone,

I need some help on identifying the kind of nutrient deficiency i am experiencing regarding the dwarf baby tears.

My tank spec:

10 gal tank
ada soil
ada aquasky light fixture( 8 hours)
co2 (3 bps)

Fertilizer dosage:
I am running on EI dosing:

1/8 tsp KN03 (N) 3x a week
1/32 tsp KH2P04 (P) 3x a week
3ml ada step 1
1ml seachem iron

Water change:
R/O water with 1/2 seachem equilibrium

Water perimeters:

No3 - 20-30ppm
GH 3 degree
KH- 3 degree

Would it be the high light level causes the nutrient deficiency?
Tank has been run for 3.5 months, the first 1.5 month, dwarf baby tears looks awesome. then, starting from month 2 to3.5 , dwarf baby tears start to turn pale, transparent and stunt growth

Any help will be highly appreciated!

Unfortunately leaving for work ATM but will look at it in A.M. but a close up of what you are calling a lack of would be helpful as those will grow sideways at will and I can't see other deffects due to too far away picture.
But I am much more famiiar/w regular baby tears though.

HC is difficult to use to diagnose a problem because it is tiny and the leaves are hard to see and photograph. If it is please post photos of the other plants.

Is this problem happening in the other plants?

What nutrients are in the step 1 you are adding - does it say on the back?

Can you post more photos of the trouble areas? A really big, really close up, high detail photo would be most helpful.

Hi guys,

Thank you very much for the input.

This is definitely iron deficiency. The Rotala plants confirm it. Read this: http://deficiencyfinder.com/?page_id=382

Yes, either get CSM+B or get DPTA chelated iron (this is better).

What likely happened here is you were adding enough iron initially because the plants had not grown big yet. After a few months they got to a point where the iron you were adding wasn't enough for the amount of plant material in the tank.

Thank you for the nice close up photos. I would like to add your pictures to the database I linked to above if that is ok with you once you confirm that it is iron deficiency? If you don't mind me using the photos what name would you like me to attach to the photos for credit?

Thank you very much for helping Zapins. I will order some DPTA chelated iron online and give it a try. I will post more picture once the plants start recovering.

You can use my photo for your database. I hope it could help the others to identify their problem too. Please credit the photos by using "Jeff Lum". Thanks alot

I'd say 0.1 - 0.5 ppm a few times a week (2-4x a week). I'd keep total weekly dose under 1-2 ppm. If you do 2-4 doses of this stuff a week you could make a weekly solution and dose portions of it. Usually iron solutions don't last too long once mixed so its best to keep making fresh batches fairly regularly. EI recommends 0.5 ppm 2-4 times a week, which you might need. You'll have to add some iron and see how the plants respond.

You can figure out how much (grams/teaspoons/etc) to use if you go to this site and plug in your tank details:http://calc.petalphile.com/

While you are on the site you might as well buy some CSM+B as well. Its much cheaper than the step 1 stuff you are using and should last you years.

Sounds good thanks!

The plants will respond quickly, probably 2-3 days but definitely within a week. White parts of the rotala will probably stay white, but the newest growth above that will be green and healthy.

Best to add just the iron first to 100% ensure the problem is iron deficiency. If you've already added the CSM+B and the iron then that's probably alright as well other deficiencies don't show up as white new leaves so it wouldn't really be one of those. It is just nice to know for sure that it is iron.

Let us know how things turn out!

1/16th teaspoon gives you 0.71 ppm iron in your 10g tank - which should be enough for the entire week. Rather than dose it all in one go I'd break it up into 3-4 doses on different days instead of dosing all at once.

And yes to answer your question DTPA iron sometimes changes the color of the water when it is dosed in large amounts. If you reduce the dose to about 0.15 ppm each time you add iron to the tank then add 0.15 ppm 3-4 times a week you shouldn't see discolored water.

So add 1/16th tsp to some water, then add 1/4th of that water to your 10g tank each time you dose. Then just do that every week.
