lack of nutrient. Can you post your setup detail, soil, light wattage, light hour temp, fert dosage, etc?
As per title; I noticed there are some brown spots on the leaves on my plants, even on my nanas. I suppose these are bad signs, but what are these exactly and what do they tell the aquarist?

Hmm, guessed as much.
Soil: Planta soil (8kg)
Lights: 2x T5 lights
Light regime: 6-8 hours
Fert dosage: Only dosing ~1ml of Seachem Flourish - Comprehensive supplement once every 2 days
Tank size? Light wattage? CO2?
Not sure how fertile is planta soil, but you miss the macro (N, P, K) fert dosing
2ft, and I can't remember the wattage on it. Yes to CO2, but it's DIY and I just found it not working last night (might be the outlet pipe problem).
Is excel necessary? N, P, K is necessary?
Excel is not necessary but NPK is needed for plant to photosynthesis and grow. Some soil like ADA Aquasoil already have N and P which probably last for a year before its depleted. Adding liquid fert will lengthen the life of the soil
So I went to buy excel flourish: Nitrogen, Potassium, Iron. Are those enough?
excel flourish Nitrogen and Potassium concentration is very low
From Seachem website
Total Nitrogen = 0.07%
Available Phosphate (P2O5) = 0.01%
so what's the recommendation? or is there any to begin with - which I think there is a range we should work with?
Since you already use seachem, you can add Seachem Flourish Nitrogen, Seachem Flourish Phosphorus and Seachem Flourish Potassium.
There are also all in one Macro fertilizer like Wonder-gro Macro. Not sure if it is still available in the market, hardly see. There are probably other brand as well.
By the way you have not post photos of your problematic plant. Hard to identify just base on incomplete description. I might totally wrong
Not plant, plants. Haha! Thanks for the advice. Let me get some photos when I am back home later tonight. Might be easier for your to diagnose.
Ok, here are the pictures. Pictures are not as clear as I want them to be as its taken on the iphone, but it should show you what I mean.
Brown edges on this plant. Can help ID also?
Some of the leaves on this plant has wrinkled, which is a sign of bad health I suppose. Need help to ID plant also (is this rotala macrandra "variegated"?).
Another picture of the above plant.
anubias barteri var barteri "broad leaf" (did I get this right?) You can see brown edges also. I went home last night and it did seem better after dosing the liquid fertilisers the previous night.
anubias barteri var nana "petite" (or mini nana? did I get this right also?). You can see some leaves are in bad shape and I want to trim them this weekend when I do my WC.
Thats better
Curling/twisted/distorted leaf can be cause due to lack of CO2, K, Ca. Ca is very unlikely, most likely due to K provided you inject enough CO2
Yellow patch or leaf turn yellow can be cause due to lack of N and K. There are many nutrient deficiency that can cause leaf to turn yellow but N and K is the major.
1st picture look like Hydrocotyle verticillata
2nd and 3rd picture look like Alternathera Reinekki

Ok, so I suppose with the excel flourish I added the plants should start doing well again?
