    Hi guys , i'm new to the forums , although i read barrreport for a year or so .


    I know there are a few issues related to plant melt but i want to ask your opinion here .


    Tank is 3 months old , 60 cm , Eheim 2071 , ADA AS , ADA Aquasky 7 hours per day , co2 3 bps , kh 3 , Ph around 6,8


    Plants MC , stauro , pinnatifida , anubias , buce , crypts and some fissidens moss.


    I dose Easy carbo (excell) daily and micros and macros every other day and 50 % water change .


    Plants started to grow well in the last month till theystart to melt , just MC and stauro , pinnatifida and anubias are doing fine .


    I couldn't get a clear picture of the plants but i found a picture on the internet and i can say mine looks 90 % the same


    Do you have any idea what is causing this ?


    Also in the red circle you can see that the stauro has a yellowish color , its not that clear green if you know what i mean


    Thanks

    Well i dose Easy Carbo 2 ml , which is normal for 64 liter high planted tank and Fe i measured 0.2 ppm


    I know how plants look when i put easy carbo on the leaves , i touched one once when trying to treat local BBA , but this looks different .


    Also these plants are in the area where i didn't treat BBA so no easy carbo near them


    Here is a picture from my actual tank , you can see the stauro marked with red .


    Also as i mentioned my stauros are a bit yellowish if you can see in the picture

    My micro solution contains the following :


    Iron (Fe) - 2 g/l


    Manganese (Mn) - 1 g/l


    Copper (Cu) - 0,052 g/l


    Zinc (Zn) - 0,29 g/l


    Boron (B) - 0,4 g/l


    Molybdenum (Mo) - 0,075 g/l


    I dose 4-5 ml each other day


    as i said i'm measuring 0.2 ppm Fe right now


    you think its overdose of something ? not deficiency ?

     


    Thanks again

    It's probably a toxicity of one or more of the micronutrients. Those are very high concentrations relative to iron. Do a massive WC, 100% if possible, and then let it grow and dose when needed.

    The only weird thing is that if i doze PO4 (from easy life) , after dozing i'm measuring PO4 1.8 - 2 ppm after 3 hours i dozed .


    The second day , aprox 24 hours later , PO4 its like 0.1 ppm


    Could it be the overdose of PO4 causing this melt ?


    I ordered KNO3 and KH2PO4 and i think will start using these next weekend after WC

    It's not the PO4. Do big water changes. Not a deficiency.

    So you suggest to do water changes and stop dosing micro ?

    The PO4 may be attracted to the soil particles which means it's adsorbed onto it. It's still there but roots now have access to it. And no, phosphate will not cause melt.

    Thanks again guys , i'll do the water changes and stop using old micro , i'we ordered chelated trace , KNO3 and KH2PO4


    Will do WC and use the new fertilezers , btw , i pruned the stauros and will see how they grow after i will change fertilezers

    Hi guys , can you confirm that transparent leaves like this here http://www.barrreport.com/filedata/fetch?id=230754 is NO3 deficiency ? which indicates destroyed chlorophyll ?


    I started dosing KNO3 and KH2PO4 and Chelated Trace and plants started to grow again without having transparent leaves , was adding 15 ppm NO3 and 3 ppm PO4 . But after 2 weeks i see signs of transparent leaves again. Maybe plants grew and need more nutrients ? My tank is 60x36x30 cm and i use ada Aquasky 601 , CO2 starts 3 hours before light , and light is on for 6 hours. After aprox 1.5 hours after light is on plants start pearling


    Maybe the light is too much and i need to dose more NPK ?


    I forgot to say that the transparent leaves are also affected by pygmy growth , at least on monte carlo


    Thanks

    N deficiency does not result in transparent leaves. Transparent leaves is a sign of metal toxicity. Cut back on trace elements.

    It's not a nitrate deficiency. But if you are not convinced, add a little more NPK. No harm in that.

    Ok noted , i will lower the micros , but i think could be N deficiency because MC has very small leaves on new growth , or im wrong ?


    Thanks again

    That's not a symptom of N deficiency. It's either a micronutrient deficiency or a toxicity, but considering that you are dosing a lot of micros, it's most likely a toxicity.

    I dosed chelated trace yesterday around 18:00 , and when i measured Fe at 23:00 it was around 0.5-0.6 ppm , but i haven't measured the rest of micronutrients

    I just find out what my chelated trace contains :


    Fe 8.2%


    Mn 1.82%


    Zn 1.16%


    B 1.05%


    Cu 0.23%


    Mo 0.15%


    I add one tsp to 500 ml water and i was dosing 10 or 15 ml in my 64 liter tank .


    Could be that this dosage of micros to create the toxicity to the plants ?


    Thanks
