I have a couple of potted sunflowers with leaf problems. The lower
leaves are turning yellow and dying on one massive sunflower and on one
of the chianti sunflowers the leaves are blotched. I put them up at:

I have other potted Chianti and massive sunflowers with no problems like
this and getting similar amounts of light. Is it a soil problem or
water? All sunflowers were planted in 16" high 12" x 12" containers.
