Last week the question was: What is wrong with these okra roots?
This plant has a pretty severe infestation of root knot nematodes (RKN). There are dozens of species or RKN that infect a wide range of plants. It can be difficult to diagnose RKN damage because the above ground symptoms can look just like nutrient and water stress, but once the plant is pulled up, its usually pretty obvious. Plant parasitic nematodes damage the roots inhibiting the plants ability to take up water and nutrients. They can also introduce diseases, like Fusarium, into the plant. For more info, take a look at this APS page.
Here is this week’s question: What kind of caterpillars are these on this broccoli leaf? (Hint: They hatched from eggs that were laid in a cluster rather than singly.)
