What's wrong with my house plants? pics included?

Question

i nurtured this plant back to life basically, when i got it it was wilting with only 2 or so half dead leaves. after it gained some strength, i started giving it a diluted solution of fertilizer with a high Nitrogen value, and then later moved up to the recommended dosage. I eventually moved it to a larger pot. But i've noticed that some areas on the leaves are dying away. Could it be nute burn? I only give it a fert solution about once every 2-4 weeks.

Answer 1

I wonder, since light waves can be red-shifted by passing through a pane of glass, for example. Have you had this plant get its light from a window where the sunlght passes through? Maybe some of the light waves had been altered ( Red Shifted) and became " Infared" and burned the surface of the leaves ....

Or Maybe not .....
