I have transplanted some corn into the fields, and the plant is turning into
a greenish yellow color. The leaves are turning yellow at the tips and
browns in, and some of the tips of the leaves are dead. There are several
dead leaves at the bottom. These plants are around 10 CM in height and they
dont seem to be growing too quickly. Where the new leaves shoots out of the
plant (at the really top) are rolling together and they turn into a
blackish-dark green color and all wrinkled. My first guesses are nitrogen
deficiency, over watering, or bad transplanting-(I can remember seeing all
the roots without clinging to the soil when I transplanted the seedlings 2-3
weeks ago). Could someone in this group tell me what action I should take to
get theses plants back to normal?

Thanks!
