sorry for the double post I put this up in general forum too
I get wavy growth in ludwigia plants such as the repens I was growing, now I just put in ludwigia inclinata var varriegated cuba, and its all wavy and does not look at all like pics
ludwigia just got put in a little over a week ago and are in process of switching to submersed
I show this deficiency slightly in my aubias, lobelia cardinlas, and just very slightly in my hygrow, leaves will tend to fold to one side or another have wavy edge, or middle vein looks like its growing faster than rest of leaf and will make wavy by puffing up in middle and then curling in towards end
tank is 75 gallon
I have 318 w all coralife lights, most of lighting PC is 67k and 4 14w t5 not HO bulds with 55k colormax and 10k bulbs I use a 10 hour photoperiod
substrate is mostly flourish black and black sand with some eco complete in as well, used over 150 lbs all together.. so its a nice deep substrate that should still have some good nutrients left in it, also I smashed up 4 root tabs and put on bottom of substrate along with some smashed bacter balls from ada.
TDS of well water is 135 usually which is relatively soft and I am told it lacks regular amounts of calcium, it may also be high in phosphates but I do not know for sure as I dont know where to get it tested.... this is usually mixed 40% RO and 60% tap, but tank usually has a TDS of 138-140 PPM
tank has been going about 6 mo
I have a large co2 system and pump about the max that I can get disolved into it, i get lots of pearling
I dose a recomended chart from Flourish and use there complete line
this is my schedule
6ml flourish comp
6ml flourish comp
10 ml excell
sun waterchange of 15-30 gallons
I looked up this deficiency in a book I have on aquatic plants and it said it was probably calcium so I started today to dose 5 ml of kent marine liquid calcium a week, this does say it is for marine but does not say no to use on freshwater and was recomended to dose calcium for inverts once a month or so in freshwater..
I was also thinking maybe I need more flourish comp than I am using..
ingredients on bottly say its deionized water and calcium chloride
is this the kind of calcium that is used in other forms of ferts?
what do you think this deficieny is and what would you do to remody it?
where can i find more in depth information on dosing for a method other than EI specifically flourish's line?
here are some pics
