Deficiency questions

How do you know what deficiencies are present when you are dosing EI?
I think that my anubias, java fern, and blyxa are suffering the most.

Here's my plant list
Ludwigia repens
Mermaid weed
anubias nana petite
anacharis narrow leaf
crypt wendtii red
Java fern windelov
S. Repens
fissidens fontanus
A.R. mini

What size tank ?
Exactly what light ? How many hrs per day ?
How much are you dosing on each fert ?
Do you have injected CO2 ?

The shortest distance between any two points is a straight line...in the opposite direction...

-Standard 55 gallon
-Buildmyled 10,000k and a Current USA satellite plus for 7 hours a day.
-1/2 tsp of KNO3, 1/8 tsp K2SO4, 1/8 tsp KH2PO4 day A, 1/8 tsp Plantex CSM+b day B
-I do inject CO2

Does this BML have a dimmer on it now ?
This is the PAR chart for that light I believe.

Let me know if it didn't take you right to it.
IF you add what is coming from it and the Satellite you have over 150PAR.
80 is enough. How much it's over shows in the leaves of the A.R. mini.

I do have a dimmer. How can you tell from the A.R. mini's leaves? I was under the impression that more light would make them redder.

That is GSA on top of them.
Fairly sure the Satellite+ has a PAR chart on-line. If you want to continue using it
you will want to reduce the BML to about 30%.
If not and you remove it, then the BML may be good at 70%.
You are using about 25% more potassium than people usually do. But if you could get
the CO2 high enough your plants might be able to use that much of it.
Problem/w that is if the CO2 could be that high it would kill fish.
This is a balancing act and the CO2 would need to be lots more higher to balance
that much light.
I would like to say that I'm basing the percent of the BML with the Satellite on the
Satellite having 35 PAR at 18". You might check that PAR rating for the Satellite and
see what it actually is at 18". And you might go 40% on the BML if it's lower than 35.
I think I remember it being 28 at 18" but not really sure on that.
You are using almost twice the Phosphate(from the KH2PO4)that is the correct amount for that tank. This nutrient can be harmful when overdone much more easily than
other nutrients.
Did you get these levels for dosing from a list or...? Almost forgot...is this what you dose three times a week ? Or is this one time each week for this list ?
If you lower the light, get lucky and have a lot of patience your A.R. mini may loose
most of the green covering those leaves.

Here's the EI scheme I was following. It was referenced on GLA ei product page.
http://www.aquascapingworld.com/maga...on-Method.html

It's impressive that you could spot that. I reduced it to 30% for now. Do you think it'd be better to just lose the satellite? I was just using it to hopefully help carpeting and the reds come out.

Thank you for all the help.

Fishophile what kind of wood is that? It's awesome. I'd like it for my new 75.

Thank you. It's a few pieces of cedar root combined. I found it at a lake in North Carolina. My journal will show a few more pictures of the different pieces.

If you dose per the EI dosing tables it isn't likely that you have any nutrient deficiency other than carbon. That's one reason we use the EI method - it leaves us with only one nutrient to adjust, CO2. Most nutrient deficiencies are CO2 deficiencies when you look further into it.

pictures of the deficiency would help, most likely CO2.

Deficiency questions

Here's a hi-jack for you: I am dosing EI, and all old leaves showing old leaves turning yellow/GSA all over them.



40-50ppm N
3-3.5ppm P
Unknown K, dosing 3x 2.5 tsp for 240 gal, 30% WC weekly Lammotte test in the mail.
Unknown Fe dosing 3x 1/4 tsp csm+B weekly
1pH drop checked At 30-32ppm co2 locked in
Lighting is 2x finnex ray 2 and 2x 54w t5ho at any given point (6kK, pink)

Do I need 5-6ppm PO4 to stop this GSA?
Is Mg deficiency a potential issue?

Thanks for feedback.

I have to keep P levels well over 5 to prevent gsa in my high light tank. Of course that doesnt explain the yellowing and overall poor condition in the pic.
