lemon seedling trouble
I have planted seeds of tangerine, tangor, grapefruit, Meyer lemon, Mexican Lime and LEMON. They are all doing well except for the lemons. They are about 6 inches high and are turning bright yellow around the edges. The edges are not dry, but appear to be more like a variegated leaf would look. I planted them in citrus mix and put them under a metal halide indoor lighting system. Anybody have any suggestions?
