    My ruffle sword and Amazon swords both have light brown patches on them, in few days the patch will turn very light brown (almost clear) and will develop holes. What could be the reason, i read iron deficency has similar side effect but it says the clearing will start from tip of leaves but mine is happening in the middle or on the edges of leaves. I have attched a picture, almost all my ruffle sword leaf are affected, pls help

    CO2 defficiency. It's scavenging the carbon and resources from the older leaves in favor of new growth. The transparency overall on the leaf with the holes in it is also a good indicator.

    Am going to say its NO3 defficiency, i induced it befor in my 29g with swords. i found that swords are not very sensitive to co2 level much.

    hi S and hani
    thanks for you reply, could it be any other things than defficiency. My drop checker with 5dkh solution is green, my Nitrate is 15ppm, potassium is 2 ppm (i don't have kit to test Fe or K) but I dose 1/2 tbls k2so4 every other day and Seacham Iron (it says 5 ml increases .1 fe and i dose about 20 ml every other day)

    My dosing in 50 gallon is:
    Everything is dosed every other day.
    3/4 tbls of KNO3
    1/2 tbls OF K2SO4
    few drops of Fleet Enema
    Seacham Trace and Fe

    regards
    NN

    i will say go up to 25ppm with kno3, the damaged leaves will not cure, look at the new leaves. swords sucks nutrient. how many swords do you have?

    Do you have Pleco's? They can do something like this. Spilled some pure drops of Excel on the leaf maybe?

    Hi,

    I am going to ask you to provide more details on your tank size, lighting, substrate, use of c02, dosing, etc before I attempt a guess...

    Is the tank mature, new, ???

    If this info is in another thread, just link to that one, no need to retype.

    IMO it is not caused by fish damage but again, want to know what is in your tank...
