Describe your problem :
----------------------
My hairgrass is not really growing very well. They are growing, however young leaves are bright green in colour and old leaves are dark green, browning and there are spots and patches of browns on them. though having they since like 6 mths ago, they are like only 1-1.5 inches tall and does not "spread like wild fire" as many described. BTW Im growing them in ADA amozonia and im using a rainbar. I have tried various fert regimes but its still the same. I was formerly using Dr Mallicks lushgro Aqua and dosing PO4 before switching to ADA

I am having the same problem as well. Been having Jap HG in my nano tank for 6months now, added these on apr =co2, daily 8hrs->12w lights, dosing 20ppm NO3, 0.5ppm po4, >20ppm K as well as trace elements, calcium+mag during wc, however, it isnt creeping like wild fire as some bros here using simple setup like lowtech.
The only difference i managed to stream down is the soil, i m using . GEX red packets [shrimps+plants soil] with larger grains. Verminator did mentioned reading that smaller grain allows the HG to creep faster given the same parameters for both tanks.
For now, i have been trimming the brown leaves since last week after my bga blackout. This as suggested by many bros here encourages runners as well.
It was worst when I was dosing lushgro back then, I am definitely maintainly 5-30ppm for NO3 and 1-2ppm for PO4.Originally Posted by Shadow
I did trim the tips as well, but they never grow taller after that..
How about soil ? large or smaller grains ?
your measurement seems to be pointing otherwise
It was then mths ago i used lushgro. I dosed according to the DMDD calculator and attained the required 5-30ppm NO3 and 1-2ppm PO4,man the condition of the HG was worst then.
It is only after switching to ADA did it turn better, more fresher green but most of it still dark green with browning and most has spots/patches of browns
The above measurements are with ADA ferts

I'm still think even with ADA, NO3 should not be 0. Unless something wrong with you tester or you dose too little.
What substrate are you using?
ADA amazonia
Im not familiar with ada amazonia as i have only glimpse the large 3kg bags at Thio and wasnt comparing them to gex powder soil.
Likewise, even with low ferts, hairgrass have done pretty well in low tech setup as observed by various bros here. So these issue of hg having problems is isolated between myself and chim?
You and me must be scratching head after such a long long time.Im not familiar with ada amazonia as i have only glimpse the large 3kg bags at Thio and wasnt comparing them to gex powder soil.

I ever thought of rescaping the whole thing. Likewise, wondering whether is it the grain size of the substrate did the difference. My friend used the same and his plants are doing well until he decommissioned his tank.
Any bros out there had experienced the same problem and managed to overcome it?
defenetly not because of the substrate, I'm using Amazonia as well.
I never had problems with normal hairgrass even in lapis gravel. Recently, I've planted my jap hairgrass in lapis. 2x1x1 tank, 55w PL 12hrs. My tank conditons since i had normal hairgrass were as follows: No considerable form of root ferts because my base fert has been sitting under the lapis for more than 4 years already. Just liquid ferts and lots of CO2 (3-4bps) via reactor. CO2 is not so constant for me, because my solenoid is a little faulty. (It doesn't let the air out every morning when it turns on, i have to turn the knob in both directions a little everyday. Sometimes i forget to do that and the tank runs without CO2 for more than 3/4 of the day.)
So far it has been 3 weeks+ (i let it sit potted in the tank for about 1 week before planting), the new plantlets are plenty, bright green and bending as they should. The old leaves are still there and they are dull and browning. Will update soon, hopefully with good news.
sigh, so problems lies with both of us.. So sad lol.
yeah man! But whats the problem? If its some problem that can be rectified, I dont mind LOL
A noobie question for all bros - the "rightful" ppm for NO3(5-30),CO2(25-35ppm),PO4(1-3ppm) etc etc is based on a daily requirement or weekly? Meaning NO3 (5-30ppm) is a daily requirement?
Update - my NO3 is 5ppm as measured this morning
Im using EI from peter's advise, so i dose around 20ppm/3 on mon/wed/sat like this. Same with the other liquid ferts.
NO3(5-30),CO2(25-35ppm),PO4(1-3ppm)... based on daily requirement
