It does look like a nutrient deficiency. Try espom salt in water. 15 ml, 15 cc in 1- 1.5 liter water.

Do you have drainage? Soil could be compact.

Epsom salt is magnesium sulfate.

PH problems and under/overwatering are often misdiagnosed as nutrient deficiency to terrible effect. Make sure those are right before tweaking with npk is my suggestion.
good luck

I've tried to correct the problem with epsom Salt bug nothing, the problem become too bigger...
Now i bought a phmeter to see if the problem comes from the ph of the soil.
Any quick suggestion? Cause i Think that she doesnt survive till the end...

True...all environmental factors have to be in place to grow a quality green plant- pH, nutes, aerated soil with perlite (if using soil), adequate drainage and lighting. No bugs, no pests, etc.

if nothing helped then its not rootbound? ...plant eat yourself for constant mass vs amount of earth

can you add a pic of the space around including the spotlight?

Well, this is not overfertilized.

It is a calcium deficiency .

Calcium and magnesium work together ( so it is easy to mess mind about what is missing ) .
2 parts of Calcium for 1 part of Mg .
If you give only Magnesium you dig the calcium deficiency .
If you give only calcium you dig the magnesium deficiency .

What is your pot contenance ? And which quality of soil ? I can't see any perlite from here .

Canna is selling a liquid calcium and magnesium for plants that are easy to use .

Do you recognized the same deficiency ? ( this picture was found on the internet to illustrate calcium deficiency )
