Dwarf hairgrass tends to lose all of its 'leaves' in the first few weeks after you plant it, and then new growth will come up from the roots. Were the plants in tissue culture before you planted them? Usually this happens when you switch from emerged growth to submerged. That lighting seems more than sufficient to grow a carpet. I wouldn't be too worried just yet. Keep your eye out for new growth coming up!

Hi
I have got a problem here
Tank - Uncycled
90*45*45 cm (3ft long)
Ada amazonia Soil
DIY CO2 (Citric Acid/BS)
Light 4 x 21w T5 (2 x 6500K and 2x 4000K)
Plants : Dwarf Hairgrass & Rotala Sp Nanjenshan
Rotala was planted after 10 days
I setup the tank on Oct 1st 2016, I did daily 50% water changes 1st week and 50% every other day on second week, weekly 50% afterwards
![]()
Everything went fine until 17th oct 2016- 3rd week; I also installed new canister filter this week (Sunsun 302)
![]()
But when I took a picture on 23rd I noticed some of the hairgrass is slowly turning yellow- but still growing; Rotala was fine
![]()
I didnt add any fertilizers for 2 weeks; I read that amazonia is enough for first few months. I started dosing florish excel and on 3rd week started using Flourish(Comprehensive)
Before it was pearling a lot, Now I cannot see much pearling.
Also I am in the middle of cycle; I started to get nitrate readings end of 3rd week.
My current readings are
0.25 ammonia, 1 ppm Nitrite and over 50 to 100 ppm nitrates. I did 70% wc few days ago and nitrates climbed back to 50 again today.
Why is my hairgrass has yellow hue. My possible assumptions
What do you think? This is my first tank;

- less water changes?
- High nitrates?
- Flourish/Flourish Excel?
- Rotala taking all the nutrients?

[*]less water changes? - it wouldn't impact the grassHi

[*]High nitrates? - prob not at this early stage of your tank
[*]Flourish/Flourish Excel? - if anything, these products should be benifiting the plants
[*]Rotala taking all the nutrients? - theres plenty of nutrients to go around for everybody in the tank
my guess is the CO2 levels and your grass is melting. have you been fiddling with your co2 levels? since the grass just got planted into the tank, it takes about 2-3 weeks for it to adjust to the parameters in the tank. If it detects that the co2 levels are low, it will start melting and once it melts, it will melt all the way till it dies. you just want to make it so that the spread of melting stops. since you ahve no fish, i would say bump up the co2 levels.

Here are some close ups, I think old leaves are turning yellow
Another change I did on 3rd week is increasing light period from 6 to 8 hours
Do I need to add macro line flourish now (Iron/Pottasium)

it is melting. it is the grass adjusting to your water. the yellow blades will continue with their melting till it dies all the way into clear see through noodles. i would put your eye on the co2 levels. make sure they have stable co2. when i say stable, i mean not changing your co2 for a week. find a good level and let it sit for 1-2 weeks. melting is normal in the beginning weeks. if your tank is good, you should start setting growth despite melting is going on at the same time.Here are some close ups, I think old leaves are turning yellow
