Should i be worried?

Jayy

I've noticed that a few of my plants have dead leaves and others have brown spots. I felize once a week like the bottle says to and measure correctly. While this is happening other plants are growing nicely and have new leaves. Whats going on?

What are the plants that are not doing well? Also a pic of them might helps as well. If the plants are still in the emerged form the leaves will die off but new submerged leave should replace them. If they are substrate rooted plants you might want to consider some root tablets for them. Another thing to consider is the lighting for them. Depending on your lighting and what they need they may not do that good. Just things to consider and info for those trying to help.

The plants that aren't doing well are one Wisteria plant and three amazon swords. Two of the look better than the third which has quite a few brown spots. I know its not the lighting,bryon helped with that. Maybe i should which fetilzer brands and pick up some root tabs.

What type of fertilizer are you using? How long have these plants been in, have you done any changes lately? What exactly is the Wisteria doing?

Boredomb

Wisteria is a stem plant and can pull the nutrients up in the water table so liquid fertilizer should be fine with it. Though I have heard people not haven that much luck with it with moderate lighting. Are the leaves falling off on the bottom of the Wisteria? As far as the brand I have heard (and use it myself) that flourish comprehensive is good.
The swords leaves that are showing problems are they more rounded then slim and pointed? If so then they will fall off. Ad that will be the emerged form. Also rooted tablets would be good for them as they get their nutrients from the substrate.

I concur with what has been posted. A photo would help narrow it down.

Jayy

Yes,they are falling off at the bottom and the swords are rounded. I'll also pick up some tabs

On the Wisteria that's a sign of light deficiency. I am not sure what to say about that other then they are not getting enough light. On the swords it sounds like it is the emerged form leaves then. They will die off and new ones should replace them.

Ok, I'll move it to a better spot.

Also some people have better luck using Wisteria as a floating plant.
