29gal just not thriving? But other tanks are?

Heys guys!

I have 3 planted tanks, a 55, a 29, and a 10. The 55 and 10 are doing great, so great nearly a weekly trim is needed however the 29gal has never needed a trim other than controlling the duck weed population and trimming anacharis.
Its been running for since Sep. 28 of this year but most of the plants aren't doing so good.
Only the amazon sword, cambomba, hornwort, klein bar sword and anacharis are doing good even some of those just fine at best.
The cardinal plant, ludwigia, azolla filiculoides, and rosette sword are either somewhat melting or barely growing.
I fertilize 2x weekly with aquarium co-op Easy Green and put in a few root tabs when I started the tank, it also has Fluval stratum, spider wood, cholla wood, and river stones.
Also has some botanicals, gum tree pods, oak leaves, and indian almond leaves.
The light is a Top Fin that came with the setup, same light as my 55gal, it's one for 8hr. daily.
Temp is 78
Stocking is 3 black skirts, 8 glolights, and 1 BN.
The filter is a HOB.
Should I increase the light period? Or decrease? Same with the fert?
TIA
A few minutes ago I added 10+ stem plants anacharis, cambomba, hornwort and fanwort from my other two tanks.

 

I have to assume light intensity is the issue. Pics would be appreciated too. The plants you said are doing well have lower light requirements than the others which would prefer medium light.

 

There’s the pics, the last two are the azolla and cardinal plants looking melted

 

I agree with Rye3434, it looks like a light/CO2 issue to me as well. Some of your stem plants may just not be suited to this tank. Some of your other plants look healthy enough though. So, if it were me, I'd replace the plants that aren't doing well with some that will be happier in this tank, or I'd increase your light/CO2 to help the plants that are struggling. Also, it is possible that removing your floating plants could help the plants below.

 

I have Co2 though for this tank I just started the system like a week ago, I look into plants that do better in lower lights too, should I increase the photo period to say 9hrs?
I've been thinking of removing the duckweed as the Glolights have been eating the roots!

 

I have Co2 though for this tank

Do you have enough/consistent CO2? If adding CO2, you should shoot for about 30ppm throughout the entire lighting period. If your CO2 is low/slowly ramps up throughout the day, that could be part of the problem. Inconsistent CO2 causes plants to struggle. I find it's best to keep it high all day, or don't add any at all.

I just started the system like a week ago,

This could be part of what we're seeing as well. Only one week is not much time. The plants may still be adjusting, and the tank is still maturing. I'd try pulling up the stem plants, cut off the dying base, and replant the healthier tops...or, similarly, cut them at the substrate, remove the dead bits and replant the tops.

You could, and this may be helpful. But, I'm not sure that is your biggest issue now that I know you're adding CO2. With plentiful CO2, plants can actually grow in even lower light than they could have otherwise.

I think removing your floating plants would be helpful.

In summary, the first things I'd try is to make sure your CO2 levels are high enough and consistent. I'd remove the floating plants. And, I'd give the tank some more time...at least a month. If the plants are still struggling after that, then you can reassess and try something new.

Alright, I will def remove the floaters, and replant the tops of what plants aren't doing good.
I'm ordering a Co2 checker for all of my tanks very very soon so I'll be able to measure how much the DIY system is putting out.
