took this leaf off, its the only leaf that turned really yellow the other is half green half yellow, some people say nitrogen deficiency some people say the soil that i have is too much nutes already in it (5-5-10) please let me know.thanks
Its just a dying leaf, not a big deal. next time just leave it be, they will fall off of their own accord. Even healthy plants may now and again have a leaf or 2 die. You don't need to worry too much unless it starts to affect the whole plant.
