twisted dwarf hairgrass?

Hi i planted my dhg about 2 weeks ago and there have been some new growth, however all the new runners are twisted almost like twisted vals.

Can someone tell me if that's normal or some kind of deficiency? if so what is it?

I am using aquasoil, current led+ and excel dosing, nothing else. Thank you

Dhg belem is supposed to have some curve to it... Is it possible you got corkscrew rush or any other eleocharis?

My dhg has also been doing that, but they tend to straighten out once they get longer I have been noticing. Weird

Anytime I've run into twisted leaves, be it dhg or giant hg, reinekii, crypts or whatever, it's always been a co2 issue.

For awhile I read a lot about k overdose blocking ca uptake and similar nutrient-centric claims, which I tried and tried without any luck.

When I finally accepted my co2 may be lower than I think, that is when I was able to fix the twisted leaf issue

Alternately, you could lower the light

it's true this tank is a low tech without pressurized co2, but i do dose excel daily above the suggested amount - i dose 3ml for 20 gallon.

i dont think i can lower my light anymore i am using the current led+ at 16" height. It's bare minimum for growing dhg i believe.

must....resist....pressurized co2

Lol, come on man, it's just gas, try some....

When I used excel I dosed it heavily, granted there was no livestock at the time.

If you're disciplined enough you can get good results with diy co2

Without a par meter, I always wonder what my light is. Best thing I've found to do is just try something. Experiment a bit with intensities and photoperiod, but you're probably right about the light

Why not try using some flourish just in case it is a nutrient issue. When I had twisted growth I was dosing heavy EI, so if you aren't dosing anything, that could be an issue.

Doesn't hurt to try stuff, just increases exp. points

Is hard to say but since you aren't dosing, I think you should dose with EI. Mine doesn't that. Either straight or some tends to curve towards the substrate. This is with my high tech tank with pressurized CO2 and heavy EI dosing, with dirt substrate.

I unterstand this topic is quite old but i'm having the same issue with normal hair grass(acicularis), how did you solve the issue?
Did more co2 help? I was dosing about 30-35 ppm with 0.5w x liter with T5 tubes and advanced Seachem fertilization protocol.
I also have JBL fertile soil with 4-6 cm od inhert quartz on it.
