Strange Leaves On Plant

[MegaZerino]

I have 3 amazon swords in my 65l tank, 2 of them are fine, but on one of them some of the leaves have gone flimsy and thinner than the other leaves on the same plant. why could this be? could it have something to do with the face that the plant is right next to the heater? (two of the leaves that are touching the filter havent gone flimsy though)

Could the roots have been damaged recently?

no, i dont/ go near them because theyre behind a rock and piece of wood, and they are deep under the substrate

How long have they been planted/when did you get them?

Yeah IME amazon swords will grow new leaves for a while and then slowly deteriorate if, in my case, the lighting is too low or if theyre not getting a nutrient that they need. So basically they live off their build up food reserves and then die if you dont have the correct conditions.
