Hi guys,

I planted my rotala indica in my tank about 4 months ago. They were extremely healthy for 3 months. I noticed since the last month the rotala are not healthy as they were months back. (29 gallon tank, eco complete and fluorite sand, 2 t5 6700k plant bulbs and 2 t5 colormax bulbs,dosing florish once a week) I posted some pics down below. Also the roots looks like its rotten or something... Please help me.

Looks like the plants are running out of nutrients. Florish (Comprehensive) is mostly micros. Even if you have 10-40 ppm of N, you still might be running out of P or K.

Hard to say what is wrong with the plants without the new leaves present. Half the information is missing.

I do see some of the old leaf tips turning brown which might be a nitrogen deficiency as SL and OVT mentioned.

Can you take more photos of the other plants in the tank and do a nitrate test on the water?

What fertilizers are you adding and how often? What type of lights do you have on the tank and how long are they on for?

Thanks for responding,
Lighting
2 coralife light fixtures: One fixture has 2 colormax bulbs and the other one has 2 6,700k bulbs. ( each bulb is 15 watts) 9am to 7pm

I dose Seachem Flourish one a week.

I will post more pics and do a water test.

He's already got the Flourish going. Not sure if you'll need Trace though, never had experience with it. I'd get the bottle of iron though if you're going to get more micros. I mean, if you're going down this route, then you might just get dry fertilizers and mix your own.

As others mentioned it is a good idea to use a proper fertilizing schedule, which includes addition of all the essential nutrients. Flourish products are extremely dilute so you should be overdosing by at least 5-10x what the directions say if you are going to use them as the only source of nutrients.

I do not think this is a micro deficiency since old plant growth is affected and most deficiencies that affect old growth are macro nutrients like nitrogen, phosphorus and potassium.

Since your nitrate readings are 0 I'd start there. Add nitrates and see if the plants grow again.

Plants can only develop one deficiency at a time so don't go crazy trying to figure out which group of nutrients might be deficient.

Also, algae is not a reliable nutrient indicator as far as I have read in the literature. Many theories no solid relationships.
