Problem with zucchini plants.....
I am wondering if anyone can help me.
I have 6 zucchini plants in my garden that are all of the sudden losing the pigment in thier leaves. The leaves look ok otherwise, just losing thier color. Not dusty, or powdery. Just loss of color. Then, the bottom most leaves are browning and the edges are curling.
At first I thought it was powdery mildew, but I have that on my bee balm and it does not look the same.
Again, only the lowest leaves, so far, are browning. The top leaves look great! Just losing pigment.
What is this? Anything I can do?
Any help is appreciated.
