Plants turning yellow (what should I do)

Hey, some of my plants have been turning yellow or brown and I’m wondering what I should do to help with it. I use root tabs for my plants.
Is their too much lighting?
Why are they turning colors? Some other plants are doing really well while some are not.

 

It might never because the you’re turning on the light too much time. I also had the same problem, make a schedule of what time to end and to start. If that’s not working it might be because the plants have a nitrogen deficiency, it’s common and there many of products to save your plants.

 

Ok, the plants are still growing but it seems the older leaves are doing this. I’ll look to see what I can do to help

 

What light and how long do you have it on each day?

Older leaves yellowing is a sign of nitrogen deficiency. It's a good idea to have a liquid fertilizer on hand.
In the 1st pic you have an anubias, which can't have its rhizome buried. Yours appears to be above the gravel which is good, but it's something to note! Usually people tie or glue them to rocks and wood.

 

Nutrient deficiency. I'd look into easy green if you're interested in an east fertilizer. I use it, works really well. also I see your anubias is planted. It needs to be only attached to wood or a rock. The rhizome will rot if planted.

 

Ok, I have aquarium glue so I’ll try to attach it to something.
I use Easy root tabs, do they have the same stuff as easy green or are they different (other than the form they come in)

Also, I have two of the same Anubias and one is turning yellow where the other one is bright/dark green. The other one is a little newer though.
I’ll keep monitoring them and try new things to see what works.

Similar. But root tabs help root growth. The liquid fertilizer will be utilized through many plants stems or leaves. Some plants like swords and bulb plants will grow better with roots tabs. Stem plants will grow better with easy green
