HI all.

While looking at my squash leaves I noticed some mottling. I was worried it was beginning stages of mosaic.

But after looking at this link

I am wondering if it is a deficiency of some sort. Calcium?

Most of my squash plants, beans and cucumbers have some of this leaf discoloration from one degree or another.

Are those at home soii testing kits acurate?

Does this look more like a deisease or deficiency?

Thanks

Jen
