What is wrong with my plants?

[gruzek]

Can someone tell me what is wrong with my plants? Is it some kind of the rot or just potassium deficiency?
Let me see if I can add my pic.

Looks like potassium and maybe magnesium. Are you dosing?

How much light do you have [acronym:e06edc4779="Watts Per Gallon"]WPG[/acronym:e06edc4779]? And what are your test results?

[gruzek]

It`s a 60 gallon tank. [acronym:124c93cc65="Watts Per Gallon"]WPG[/acronym:124c93cc65] is about 3.5.
[acronym:124c93cc65="Carbon dioxide"]CO2[/acronym:124c93cc65] level is 19 [acronym:124c93cc65="Parts per Million"]ppm[/acronym:124c93cc65].
I use Chuck`s calculator to dose nutrients.
K2SO4 - once a week 20ppm
Plantex+B+[acronym:124c93cc65="Iron"]Fe[/acronym:124c93cc65] twice a week 1.5ml ( 1 TBS in .250ml of destilled water )
I checked nitrate level - 13 - 15 [acronym:124c93cc65="milligrams or magnesium, depending on context"]mg[/acronym:124c93cc65]/l
[acronym:124c93cc65="power head or Measure of the concentration of hydrogen ions, depending on context"]PH[/acronym:124c93cc65] - 7.0
no clue about magnesium

You certainly have enough [acronym:131e1bf5e1="Kelvin or Potassium, depending on context"]K[/acronym:131e1bf5e1]. Do you know your [acronym:131e1bf5e1="General Hardness"]GH[/acronym:131e1bf5e1]? You may have seen this page already, but if you have not: http://www.csd.net/~cgadd/aqua/art_plant_nutrient.htm Here is an example from a quick google search, but a terrestrial plant: http://www.rhs.org.uk/advice/profile...deficiency.jpg

You can add 1 TBS MgSO4, Epsom Salt, to your trace mix bottle per Gregs Plantex howto.

[acronym:71a8c83a31="General Hardness"]GH[/acronym:71a8c83a31] is 5.
All those clear spots I see only on heavy root feeders. Two leaves in my pic is anubia and red sword. I got`em from my friend where they were doing great. For 10 days after I planted`em in my tank everything was OK. Just for the last 4-5 days I started noticing clear spots and tiny holes especially in anubia. I make my own root tabs ([acronym:71a8c83a31="Poor Mans Dosing Drops"]PMDD[/acronym:71a8c83a31] + clay) and I put one or two close the roots.
I`m really confused - have no clue what is wrong.

I'd agrees with the lack of [acronym:8d95e3a7d4="Kelvin or Potassium, depending on context"]K[/acronym:8d95e3a7d4] and [acronym:8d95e3a7d4="milligrams or magnesium, depending on context"]mg[/acronym:8d95e3a7d4]. YOur Co2 is low also. Try to get it up to 30ppm. This will in the least keep algae at bay while your plants recover. I would also remove those leaves.

[Tiffi]

Because of the appearing pinholes and since it are older leaves I would still say it's a potassium deficiency.

@simpte: if the whole plant looks like that, what do you want to remove - the whole plant? And why except for looks would you want to remove it? It's not a disease.

[gruzek]

OK. What do you suggest, guys? Anubias and red swords are root feeders.
Should I put more root tabs near roots or increase [acronym:28c5d00e14="Kelvin or Potassium, depending on context"]K[/acronym:28c5d00e14] in the water column?

[Hoovercat]

[acronym:660ab2fe23="In my opinion"]IMO[/acronym:660ab2fe23], you shouldn't change anything. As you say, it's only the heavy root feeders that are suffering. These guys may only be showing a delayed response to being moved. I say prune back the badly damaged leaves and give them a couple more weeks to re-establish their root systems. From what I gather you've got gravel substrate? If so, give them a chance to get their root system over to your "pockets" of gravel heavily fertilised by your root tabs.
