hello!
having a nice crop of spinach just lately (first time ever!)

it's not a big deal, but i was wondering if anyone knows why some of my
spinach plants get "bubbly" leaves - it's as though the edges of the leaf
stop growing at some point, but the bulk of the leaf continues to expand, so
you get a wavy sort of surface to each leaf on the affected plants. some
plants are like this on every leaf, others not affected at all. the cultivar
is "medina" fwiw.

thanks if anyone knows!
